It is the Swarf in the system (which can only really originate in the HP Pump) that causes most issues, according to my local Delphi agent and he reckons that in the case of the Mk3 at least, they have not done anything to rectify this problem on replacement pumps.
Who actually manufactures the Mk4 fuel system and is it any better.
On the mk3s there was a few diffrent setups depending on final bhp and model, The facelift 2.0 115bhp models had the most issues, most costly was the faulty wastegate ecus that were getting killed by heat and you could only get a new one by buying a whole new turbo at £1500 lol.
My mate who words for ford said thay fixed alot of the mk3s issues on the mk4 but not all.
tbh mate most dervs suffer with fueling issues i had a vectra derv only 2 years old with only 40k and after two weeks it cost me £2500 in total to find the issue and fix it which i had to have alot of the fuel systems.
Couldnt say who made/designed the fuel systems and weather or not thay have changed.
