Hi, I am having a few fuel pump problems on my 2007 new shape. The hand pump is losing pressure and I am getting some chugging when driving. The bleed screw appears to be well sealed and there is no air/diesel leaking when I pump it. Likewise, the pipes appear to be well sealed with no fuel leaks. If I press the hand pump a few times it gets to a decent pressure but when I start the engine and run a few miles I lose it. Is this a common problem? What could be causing it? Is there a straightforward fix that I am missing? Any advice would be appreciated. Thanks Sean

Ok, tumbleweed....... I suppose the better question is, once I have fitted the new filter, what is the best way to ensure all of the air is out of the system so the hand plunger is solid and stays that way?

 When you fit new filter on B40 it is best to take filter completely off the wing and change filter on the bench to ensure good seal, simple remove two nuts, disconnect two pipes and disconnect wire to water trap. to bleed air from system , loosen the bleed screw at side of filter, pump by hand until no air bubbles come out of bleed screw. when clear diesel only hold plunger down and tighten bleed screw

Thanks Bootsie.... had a bit of time to investigate it today and I have diesel leaking from the seal on the white plastic part which screws into the bottom of the filter. It looks like the part itself has become worn and damaged over the years so it probably needs replacing. I will fit a new O ring for now but do you know what the part is called for when I order a new one? It screws into the bottom of the filter and the wires run out of it.

Things not going so good.... can I hand pump the fuel through without topping the filter up? When first fitted I have tried to reseal everything but still losing pressure and the truck is misfiring. I have diesel all over the driveway......

Vacuum pump should get it ok, so long as there's not too bad a leak.

had the filter off and on again and everything seems to be well sealed however it is still running very badly. It is misfiring/chugging especially at low speeds. It must be a fuel problem but I just can't work out what....

If your EGR is partially stuck open it will gutless at low rpm. Make a temporary EGR blank plate and see if the problem goes away. Do a search on SCV (Suction Control Valve) and see if those symptoms are similar too.

Yes, could be the problem.... I am waiting on delivery of a new filter and I will try that first before I move on to anything else. I remember thinking something wasn't quite right when I put the last one on a couple of months ago (it made a cracking type noise as I tightened it... can they be over-tightened??). Truck has been sat on the drive for the last two days and I have been on my push bike to work..... 19 miles each way  Cry Cry Cry So I will be glad to get it back on the road again. I made the mistake of buying a Bosch filter from Halfords on Sunday because they guaranteed it would be in store by Monday. When I went to fit it last night the thread was knackered and I had to abandon the job and order another from Milners. Should be with me tomorrow night
