Fuel Problem I Think

the main return is just open to the top of the tank,if it runs bubble free when running thats all that matters, if you have clear plastic before lp and then between filter and inj pump that should show something

Yeah it does have clear pipes in there. It had them at the pickup pipe to main fuel line. At the lift pump to main fuel line. Lift pump to fuel filter is all clear. Fuel filter to FIP is all clear too. When it runs, the small amount of fuel we had coming from the tank was bubble free. The fuel coming out of the lift pump wasn’t, but there wasn’t a great deal being pumped. It had quite a bit of pressure as when you opened a join, it had quite a surprising “HISS”.

If the lift pump was working as it should, do you think it should be able to “suck” fuel from a Jerry can and run the system? I know the FIP can do it through the fuel filter, but the lift pump wouldn’t suck from a Jerry can.

Yes, it should - but why the **** you've got 3 LP's which appear fubar is a bit :confused: .... If the system is air tight, I've known the FIP manage to keep up with demand with a kaput LP - at this point it takes a tiny amount of air in the system, and injun no run :rolleyes: ..... as had been said before - the usual pointer to this is a half full fuel filter .....

@border Put some piccies up - this is getting daft now - so I'm sure you're fed up to the back teeth with it.. !

lift pump should suck from a can and bubbles after leads to the lift pump as most likely culprit,probably find many like that nowadays but because inj pump can cope with some you never notice

Just about ready to throw the towel in Mate, will get more pics and Vids today.:(
 
When I took filter off last week both times it was full, just fired it up and hardly any fuel in pipes, took it off now and it's just about empty , filled it up and now it's just running from fuel in the filter but with the usual bubbles of air, there's nothing getting through from the tank for some reason. Got to nip away for a bit but will be back at it later to try something different. Thanks everyone for trying to get this Sorted don't know what I would do without you lot helping me. :)

Get a length of clear fuel line and put it in between other parts of the fuel line, to see where you are picking air in from.
 
Gonna get another filter Housing as mentioned earlier the threads on bleed screw are fuc!!!ed, and air is still getting out very slightly, so will see if that makes any difference.

Dont think there is any other parts , the whole lots got clear line on now and Bubbles in every one of them :eek:

If you have to replace lift pump, get a Delphi brand and there is a lot of info on here as to fitment, or ask any of the guys.

Put a different filter housing on bleed screw not leaking anymore. Now just the same. It is NOT Pumping fuel from Tank, Tried from Jerry can again but still won't pump it from that either.

A couple of vids it might be worth watching - First one mentions the spacer ......

the bloke in the first vid is a thick ****, if you fit a thick enough spacer so manual lever will pump at any position of the cam then obviously the cam is no longer operating the lever enough to move the diaphragm,spacers are solely to fit tdi long lever pumps to earlier engines
 
the bloke in the first vid is a thick ****,:D lol. sorry couldn't help laughing, you know what they say, if you don't laugh you cry.


Just on my own again today so just guessing at things to try. don't know what I'm doing really but never mind.
Got better filter housing so thats ok now.
Right Do these 2 vids give any more clues ?
First one for the very first time I managed to get a bit of movement on the LP, could feel the difference when priming, BUT the dam thing was only trying to push whatever fuel was there Out instead of sucking it in from the Tank.
Second Vid every time I start it now, nothing comes through from Tank, loosened bleed screw and it does try but goes back after a few seconds.
Can anyone make any sense of that lot coz I fuc***g cant :eek:

LP. It should be sucking fuel from the tank better than a Henry - When you open the bleed screw on the fuel filter, I would expect you to get rather wet with diesel ....

Funnily enough, I've replaced an electric LP on a 1104 Perkins today - and hadn't got the return from the FIP seated correctly - it sprayed fuel bl**dy everywhere :rolleyes: ... so I'm back to what I said in post #72 - I suspect you're wasting your time with the Bearmach ones :( .... :mad: Paddocks have the Delphi for £22 ....

So are these last 2 bearmach ones faulty ? or just not working as they should, ? the motor factors where I got them from when I told him the first one was not working, he said that they would have to send it back to Bearmach to be tested, then if found faulted I would get a refund, Dare I tell him Im bringing them both back ? or do I get on to Bearmach direct. :rolleyes:
