in this piccy , the input pipe to the under bonnet pump has a T piece

one must come from the tank

but where/what is the other pipe for/from

Trying to track down how my new UB pump is sucking air in and maybe causing my dicky starting

Not manage to find a decent Diesel Fuel system picture anywhere so far , Rave is just too disjointed

Sucking air ? i doubt ;but as soon as a small fuel leak appears ,a strong smell follows !

Is the ITP purring ?

Remove the filler cap an listen closely..

Chris there is a pressure relief valve on the outlet side of the UBP after the fuel filter, and that is where it plumbs back into the inlet side of the pump.

Never mind there is another way (electrical ) to check the pressure (both LP pumps)

Cheers Mike , I remember this one of yours now..

Are your wires the same colour as mine ??

can't quite make them out from your piccy ?

Chris

Also just got my Delphi clone to connect to the car and it reported 2 error codes P1260 and P1255
