ABV-VR6 12 Posted January 31, 2023 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... Quote Share this post Link to post Share on other sites

Sent from my SM-G960F using Tapatalk 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.

_Matt_ 26 Posted October 22, 2023 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. Quote Share this post Link to post Share on other sites
ABV-VR6 12 Posted October 22, 2023 That's really unfortunate! Those VDO are just no good anymore, they all cracked... Hopefully the return goes well and you find a replacement! Quote Share this post Link to post Share on other sites
_Matt_ 26 Posted October 24, 2023 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. Quote Share this post Link to post Share on other sites
