2007 Citroen C5 Problem

The Problem:

Wont start after being parked up for 5-6 hrs
Primer bulb empty and would not prime i assume a non return valve inside not wetted so would not seal.
dissconected return line fixed clear pie a nd sucked.
Fuel appeared and the primer bulb then works.
Drove 20 miles parked up 4 hrs car would not start without help from primer bulb which once again felt dry.
Am assuming as there is a small vent line to the pump area that if there is a NRV in the primer that was not workeng the vent would allow fuel to return to the tank.
Any help would be greatly appreciated please.
regards Tony

Suggested Solution

there may be a nrv in the filter housing/primer bowl it doesent take a lot for them to play up try sourcing a second hand one and try your luck
check your fuel injector link pipes they can perish and cause fuel to run back causing starting probs
