COOL , sounds like you have identified at least one problem! Fitting a 12 volt helper pump should also give you some more poke! After you get your r/worthy done you can adjust a few other bits and pieces for more power!

I put mine between the tank and hand primer, cut the rubber fuel line about 2 or 3 inches after the steel line ends near the firewall and slot it in there.

In a Pickle again.. I'm wondering if I've got a leak in my filter hand pump or water trap.

I changed the filter a couple of weeks ago, started it straight away idled for 15 minutes and turned it off,
3 days later started it to take for a warrant and it starved of fuel and died whilst idling!
I ended up dragging more fuel through and getting it going, took it for a decent drive to check it and all good.

A few days later started it up to take for a spin and same thing happened, died whilst idling ..
I took filter off and found a smaller seal (pictured) under my truck which I presumed was meant to be in the filter as if fit perfectly??
I reinstalled the filter.. tightened it a bit extra this time, replaced spring clamps with hose clamps on fuel lines, dragged more fuel through and she ran sweet. Again I've taken it for a few 10 - 20k trips, all good!.
P1060400.JPG

Missus took it out on a short trip yesterday and when I came back I got in it to move it and same thing, this time it was idling ok but I got out on the street and it started starving of fuel again..

I've taking the filter off again, the water trap had probably 1/4 of a turn in it so I've cranked that!
The hand pump has never really worked on top of the filter it never pumps up firm so I'm wondering If I should replace the whole unit?

I'm just hoping its not the pump!!!

Cheers in advance!!

Definatly sounds like an air leak. You can dismantle the pump and clean it. Mine stopped working because of a small flake of goo under the inner flap Otherwise the 3 orings in the filter are the only seals. Also look at your rubber hoses for splits at the ends.
Other common fault in older pumps is the front seal on the pump. This can be replaced without removing the pump but the pulleys do have to come off. There was a suggestion that a temp fix is a electric pump in the line to stop it sucking air but Lewis did this and a couple of months later it dumped a tank of fuel through that seal so I dont recommend it any more

oops I might stay away from that then..
I was thinking of fitting an electric pump or a hand squeeze pump before the filter so that filter changes go a bit smoother.

I was thinking if I had a electric pump I could switch it on for first drive after a filter change just to get going a bit quicker then turn it off again, I dont know if diesel still flows through those inline pumps when their turned off?? A hand pump would do if not..

Well hopefully if I can find an air leak then I might solve all my problems anyway.. I'll have a look now, if no luck I might just buy a new one.. ($60ish off ebay)

There is a rubber o ring in there I had the same problem at the time I couldn't get the proper o ring so I put some gasket stuff around the out side o ring after I took it off and let it set before I done it back up again has been fine so far.
if you need the o ring most diesel shops should stock them for bosh pumps.

Most diesel shops will tell you it needs a full rebuild but when you explain the car is worth nothing and that you have only enough money for the one seal and you have a competant mechanic to do the job for you they should come to the party. Can you get to the seal without moving the pump?

just use a normal o ring in there, there is the same plate on the other side also, is hard to get off as the block is in the way, also are you sure its coming out of there and not the top plate gasket?

Cheers guys..
Looks easy to take off.. just 2 X 10mm bolts (maybe12mm) by the look of it..
Definitely looks like its coming from there..I'll take it off and take the o ring with my tomorrow to tr and get a replacement..

Bugger just replaced the seal and still dripping..
Its hard to see but its dripping down from the block side and running underneath the pump and forming a drip at the lowest point, right on the seal I replaced!
It could be dripping from the apposing seal its very hard to see..
Looks like I'll have to take the air intake manifold off to get a good look..
If I do that do you reckon I can get to that seal on the other side without having to take the pump off??

Cheers Guys

As i said 90 percent of the time it leaks out of the top plate seal, normally the plates have allen key bolts but if yours has bolts you should be able to get the plate off with manifold on, i cut a allen key down to fit it there, its far better to remove the whole pump and reseal it and refit it, thats what ive learnt anyway
