Replacement Fuel Pump - VR6, 2015 and onwards

[ABV-VR6 12]

All of those discussions and i still feel like I'm at square one! I thought I would splurge and get the VDO, now it's a no go... Never been a great fan of JP Group. All the info is confusing as hell...

Oh I see flow rate and pressure are related.

No, you need enough flow to meet the consumption of the engine factoring in any restriction - FPR controls the pressure and in this case is the restriction.

1 uk gallon is 4.5 litres

If at 120 mph (2 miles per minute) the car does 4.5 MPG (I’ve no idea what mpg a Corrado does at this speed, it’s just a convenient number for mental arithmetic) it will need a minimum supply of 2 litres per minute to prevent starvation, so the pump needs to overcome the 4 bar FPR the the ecu is calibrated for (excess returns to the tank) and still deliver over of 2 litres to satisfy the engines needs.

Just to update the thread. I bought a VDO and have the same cracking. Awaiting to send it back to autodoc. Could strip it but at £250 I'm not fancying that plus I doubt it is a new part, and likely to have sat around for ages. 

Cressa I think I will try the Lucas - do you have a the part no handy? The link in the thread has broken with age.

That's really unfortunate! Those VDO are just no good anymore, they all cracked... Hopefully the return goes well and you find a replacement!

Cheers ABV, I still haven't sent it back. May well just strip mine and take the pump from the new VDO unit unless I can find a better like for like replacement. I have until December to make the return with autodoc.
