Good to see its all fixed DeeJay!!
Mine surges a little sometimes when I'm flat out up a hill - is this the kind of thing you had before? I'm wondering if I should pull out the filter... my sediment tank did have some crud in it.....

I would highly recommend looking at that primary filter, its a squeeze between the engine mount & the bottom of the fuel pump.Quote:

I decided to clean out my sedimenters (twin tanks) which had a bit of crud on the base but not too bad-checked small mesh filter at bottom of lift pump which was okay- though not much fun trying to get it screwed back in. I bled the system with hand primer pump but when priming i did notice fuel leaked past plunger whilst hand pumping-is that normal? I do plan to fit a 30 micron filter between sedimenter and lift pump but going to be difficult to mount anywhere.
Fuel leaking past the primer isnt normal. Mine used to do that too. Changed it and it doesnt leak now. Was hoping to get improved performace asuming it could have been sucking air previously, but it made no difference. Just less messy to prime now.
Here's a pic of one of the simplest improvements I've made. A simple in line filter. If you're on a trip and it needs replacing you won't have trouble buying another.

I've tried a CAV type filter but was a bit difficult ensuring it was air tight.
I've tried a Racor spin on filter to replace the sedimenter which worked well but blocked. Replacement on a trip was difficult to obtain.
The sedimenter does a great job at trapping bigger fragments and would recommend it be retained.
I agree-you wouldn't want to get rid of the existing sedimenter because they do a great job for the larger particles/sludge/water etc but putting a decent filter between sedimenter and fuel pump mesh filter would be a a good move and stop the mesh filter from getting clogged up and remove the hassle of trying to remove it for cleaning.
Just installed a small filter like this, on your recommendation. Although the primary filter under the lift pump was no where near as hard to access and replace as I'd anticipated. It was partially clogged with bits of paint etc.Quote:

Careful with the small in line fuel filters like that. I have see a few get sucked in and cut off flow.
This style is still very easy to get and rated for diesel.

Funny you mention that. Yesterday, about 100km after fitting a plastic inline filter (ment for petrol )between the sedimenter and lift pump, the engine sputtered and died going up a hill under moderate load and wouldnt restart. The primer pump when operated by hand would not pull fuel through to the bleed screw. I removed the inline filter and blew through it it. It appeared to have some sort of initial blockage and then cleared with a spurt of diesel. Replaced it, pumped the primer a few times until fuel came from the bleed screw and away it went, running better than ever. All up, only out of action for about 10 minutes, but still embarrasing.Quote:

Edit: the one I used looks very similar to the one in the link, but is probably not rated for diesel. Would a diesel rating make any difference - I had assumed petrol was a stronger solvent and would be harder on a filter?
what's the ID of the fuel line so i know what size filter fittings to get.
