Ummm good question probably around 1 or 2mm - don't want it to heavy or could make bland door stress out the cables.

Good luck with that mate- sure just change the pump but I would take the whole unit off and give it a good clean and inspection, might as well get the bracket powder coated as well. Might as well do your heater box blend doors as well mate if you are doing the matrix. Im seeing alot of people doing these recently and going to a lot of hassle but not taking enough time to find a good product to refoam the flaps and using all sorts of material from furniture pads and hobby craft foam well this stuff is not designed for a heater box how long will it last ? Well I would use this stuff personally specific to blend door. https://www.ebay.co.uk/itm/Neoprene-EPDM-Blend-Foam-Adhesive-Backed-Squares-Strips-in-all-sizes/401911257667

Arh thanks that makes sense. Managed to fix my intermittent main beam light today was only working on one side, uprated headlight loom inspected the relay was rusted out and changed - after still didn't work and then realised there was a yellow fuse in a black plastic retainer inline with the external cable- changed that now working perfectly result!

OK will do chap, the only thing I think needs a bit more research is the middle insulation 20mm as the OE stuff looks better quality- has more of a dense sponge texture then the Heritage stuff. Bizarrely this dutch seller has some new old stock left rear footwell insulation 20mm bottom section in rear as no grey cell in rear footwell. Gives you a good idea of how it looks and you can see some of it cut out to fit round the floorpan pattern. https://www.vagonderdelenhuis.nl/product/demping-voor-bodem-art-nr-1l0863955/ Its sort of handy with the heritage deluxe insulation as you double up or single on the layers to suit the pattern.

Possibly but the K Jet injection system is very complicated and troublesome and to modify could spell trouble. I would just change the pump and fuel filter + fuel line and if still not good the accumulator. Why VW never made a splash shield to cover the whole unit I never know, maybe it would of been to low and would of scrapped.

Wow they put the car up with a line out of 20 stunners its good to see the Rado getting up there.

Sure will FLA it is the top layer so will be cool, I have a heat gun that should do the job and will be able to do it outside of the car for safety. I would also say it acts as a damp proof course. This insulation would have to be hard wearing and the OE stuff certainly was. #

Hi . The unit (housing for fuel pump swirl pot) is obsolete part number 535201043. These are prone to crack and leak with age. Its an area that is worth tackling as a whole for the long run if that is your plans for the car. The area basically has a Bosch fuel pump + Bosch accumulator + metal fuel pipes + Fuel filter and heat shield + housing bracket + metal fuel lines. You cannot buy the bracket or swirl pot housing its obsolete also the bracket that holds it to the car. You can just change parts in it ie fuel pump, accumulator etc. I believe this is the fuel pump you'll require. Not worth going for a cheap alternative. https://www.ebay.co.uk/itm/New-Genuine-BOSCH-Fuel-Pump-0-580-254-033-Top-German-Quality/193238953604?epid=248858159&hash=item2cfdf06e84:g:nd8AAOSw8yxcrSdu Bosch accumulator again do not cheap out on substandard alternative. https://www.ebay.co.uk/itm/VW-GOLF-MK1-GTI-MK2-16v-FUEL-PRESSURE-ACCUMULATOR-REGLATOR-A1426/223625536105?epid=1443050346&hash=item34111ee269:g:sr4AAOSwvA5dTA02 Here is a diagram of the area. http://www.oemepc.com/vw/part_single/catalog/vw/markt/RDW/modell/COR/year/1993/drive_standart/76/hg_ug/201/subcategory/69000/part_id/3687212/lang/e#sec_37 Its an area that a lot of people will dismantle and get the brackets powder coated and new fuel lines as it is open to erosion been under the floor pan of the car. I've seen this for a MK2 golf 16V and it comes complete with the pump,accumulator etc. I don't think it will fit the Corrado though because it has different swirl pot housing for the pump, all the rest is the same though, mint bit of kit with an alloy swirl pot. https://www.classic-vw.co.uk/mk2-golf-fuel-pump-housing-kit-191201043-21354-p.asp This is an example of a Corrado one in Germany for sale which is typical can see cracks in the unit and the eroded parts. https://www.ebay.co.uk/itm/VW-Corrado-16v-Petrol-Pump-Catch-Tank-535201043/283656283824?_trksid=p2485497.m4902.l9144 Thankfully in the VR6 the pump is located in the tank however can be a bit of a smelly job and it has a tendency to have rubber parts dissolve in the fuel tank.

I actually think what I have been calling a rubber layer is actually bitumen and you heat the layer on the back and then stick the insulation almost like a roofer , could be wrong though. I would rather just use glue as the Heritage stuff looks like hay. I think the new rubber layer is great just a shame it does not come in wider panels as only 250 mm x 500mm . Can see on Storm warnings picture the bitumen where it joins the insulation has been heat melted to fuse them together.

Thanks Storm Warning its not a bad price to be fair. Got to say the factory insulation is pretty impressive with three different layers. Sure the new rubber material might be able to use on the sides of the original floor insulation to fill in any gaps, even under the rear seats etc as its only 2mm deep so I imagine you could fit it to alot of places with ease of installation with the adhesive backing.

Sorry I cant vouch for the new rubber material but the old one is about 2mm and the new stuff has an adhesive backing so you can glue the insulation under it I imagine. I've got some aerosol trimming glue Im going to use and the old rubber has nothing wrong with it , just need to strip the old insulation off ang lue the double layer of Heritage deluxe to the bottom of it.

Yes the grey call is the base layer but only in the front footwells.

So if you want to go for stock for footwells Front Bottom layer x2 grey cell in each footwell (four all together) Partnumber: 321 863 863 https://www.volkswagen-classic-parts.de/en/daempfung-5600c3.html Middle layer 18-20 mm depth insulation Top rubber layer with adhesive backing layer 2mm depth Part number 323 863 950 Rear footwell Same as above but without the bottom grey cell layer. Glue them all together and you have a stock sound absorber.

This is the grey cell like material I have in the front foot well that is glued to the floor pan. You can still get them . Mine are fully intact so no need for them. They only came in the front footwells from factory. https://www.volkswagen-classic-parts.de/en/daempfung-5600c3.html

Did you template the old stock insulation ones you got out the car mate ? Think you have to do this as the stock ones have different depths to go round the floor pan pattern. Mine is the OEM carpet chap so not to worried about.

Hi, Please may I ask what is the white push rod above the battery that is located on top of the wing inside the engine bay, I see it has a cable attached to underneath. Must be some type of switch to indicate the bonnet is open or closed ? Its basically in front of the power steering reservoir. Thanks

Great the Heritage stuff should work fine then if doubled up (deluxe set) If you're looking for a 2mm sound absorber to get that little bit extra, I looked at the Corrado part number and this is what is has been superseded by . You get 6 sheets and is described as sound absorber. Probably cheapest place to get it would be the stealers. You could use this as the membrane on the top.

Thanks for the photos. Is that one piece or two pieces of the Heritage stuff that you are comparing to the VW OE insulation thickness. If it is one piece looks spot on if doubled up Thanks

The heritage under bonnet insulation is like a vinyl it is so far from been oem, It is not even the exact shape either you have to trim it. I had my under bonnet spotless and fitted it with the glue they supplied. After I fitted I just looked at and thought that just looks horrid, ripped it off and threw it in the bin- the glue they supplied its like a hard glue that I couldn't get off, was really p,,,, off to be honest waste of time and money. I'm not sure if the group buy was the stuff Heritage is selling , have a look at your under bonnet insulation and if it looks more suitable to make a gimps mask do not use it. Do yourself a favour and buy this stuff UK buyer. Has option of 10mm and 20mm https://dreadnoughtcustoms.co.uk/products/vw-corrado-bonnet-lining-2?variant=12562635915349 If the Heritage stuff is just crap for floor insulation and the measurements are not correct i'm just sending it back. By there measurements 2 pieces will be the same as OE as I have measured mine and the insulation is 20mm - must war you the oe insulation does not got right to the edge of the floor pan probable at least a 5 cm gap from the sill. Problem with some of these aftermarket material is exactly that it does not look the quality of OE . I found the C pillars where my major rattle, pulled them off and put some new cloth around the clips that house it, major difference.

It looks great but I couldn't justify spending that much money. You do realise its 325 dollars just for the footwells not including shipping and customs ? At the end of the day factory insulation has lasted 24 years and would of lasted longer if it wasn't for my matrix, it has also protected the carpets Im sticking with OE style. Im glueing the Heritage insulation to the rubber once I've stripped the old insulation off. Also you will see the insulation on the back is glued in several sections with different depth, which you can also use as a template for the new insulation to fit round floor pan pattern. I actually like the rubber as it stopped the matrix wrecking the carpet and the insulation under it mopped it up. Storm Warning please may I ask what is the Heritage stuff like, if it is anything like their under bonnet insulation Im going to shed a tear ha.

I stripped mine today. The insulation depth total layer was about 22mm. Was cut in some places to go over the floor pan pattern in the rear footwell. I had a very thin plastic grey insulation pad that had cells that was glued to the floor pan, then about 20mm of insulation with a rubber topping. They were smelly and damp with pink coolant from a previous heater matrix leak, so glad I pulled them out. The drivers sides were still mint to be fair so just left them, no point strippping out trim unless you have to as always a risk of damage to them. My carpet was pretty clean and didn't feel the need to remove it completely as the top layer rubber of the old insulation had protected it. So I just stripped enough interior so I could lift the carpet up from the footwells. In other words I didn't fancy stripping the centre console . I gave the carpet a detergent clean with a VAX dry and wet and came up great. Just waiting for the standard 12mm insulation from Heritage and going to double up the pieces (glue together) as only doing the passenger side that was wrecked by the evil matrix spewing. I would use a flexible insulation that you can cut out to suit any non flat surfaces in the floor pan. Purchased this from Heritage but I would look elsewhere as probably not great. https://cdn.shopify.com/s/files/1/1613/6135/files/CORRADO_UNDERFELT_KIT.pdf?6289193082729557112 This looks good stuff and will leave you room for a couple of mm for a thin base sound absorber. Also seller has loads of other materials. https://www.ebay.co.uk/itm/1m-x-1m-20mm-Classic-Car-Insulation-Restoration-Floor-Sound-Proofing-Deadening/252376923704?hash=item3ac2d63e38:g:e6wAAOSwGpBdssMe This is where you fit it same as factory. https://cdn.shopify.com/s/files/1/1613/6135/files/CORRADO_UNDERFELT_KIT.pdf?6289193082729557112 This is Corrado factory insulation which is the same I removed from my car. Insulation with a rubber top. https://gramho.com/media/2175337963016226635 I'm going to remove the destroyed insulation off the rubber and glue the new insulation to it as will be a perfect template and has also insured the survival of my carpet over the last 25 years.

Good stuff not sure a domestic washing machine will do them any good then due to size.

This probably much better stuff then Heritage, Flame retardant as well if your ever doing some welding up on the sills or floor pan. I would guess the Heritage stuff is none of this sort of regret buying lol. https://www.ebay.co.uk/itm/3-0m-32ft-Car-Insulation-Self-Adhesive-Foam-Sound-Deadening-Vehicle-Floor-UK/254371043759?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D40733%26meid%3D5efea0792ae9425b93e2921806a1e606%26pid%3D100290%26rk%3D4%26rkt%3D4%26sd%3D303377411805%26itm%3D254371043759%26pmt%3D1%26noa%3D0%26pg%3D2060778&_trksid=p2060778.c100290.m3507

FLA do you have to glue the first layer of insulation to the internal floor pan ? Thanks
