It seems that when the tank gets to about 1/4 the fuel is running back to the tank, i wondered if anyone knows what causes this so i can get repaired, rather than just put a non-return valve in and disguise the problem

any help appretiated.

Hello. Check out the other threads on here but i think you will find it is the fuel return pipes on the injectors that have gone hard and perished allowing air into the system. This is an easy repair and cost only a few quid. Hope this is of help Luke

This sounds like the seals on the fuel pump. Stick a nrv in the line!

Fuel will not run back if you don't let air in at the top, replace your leak off pipes first as they are cheap and easy to do (these are the pipes that link each injector to the next and then back to the pump) and will almost certainly cure the problem. IMHO a non return valve is just curing the symptoms not fixing the problem.

i thought the same im sure i have read the same symptom somewhere else, are these seals hard to replace, the car is sometimes cutting out when turning corners etc, not sure a NRV would stop that because it will still let air in.
It is perfect with a full tank but im worried if i need to go on a long journey, can these seals be replaced??

cheers for the advise.

i think these pipes have been recently replaced on a service i am going to check receipt, but i only have the problem when the tank is quarter full or less, so surely this means a tank problem!!
