i have pulled the fuel pump out of the tank today to inspect it, and it was clogged with loads of black crap and bits of blue plastic?? anyway i have disconnected the elctrical wires and the fuel hose from the top plate to allow it to come out. i have then dismantled it further which resulted in me removing the fuel pipe from the top of the pump itself, not sure if i have done right here or maybe gone a bit to far, i cant get the filter of the bottom and cant seem to release the pump/filter from its immediate plastic surrounding. Not sure if this is as far as i can go or whether i have gone too far at this point. what should i cklean the pump/ filter with. obviously being blockedthings should be better when it goes back together if i can remember how it all fits together?? HELP!!!!

Quick update. Finally got the swirl pot out of the tank and as said in the how to thread, it is a bitch to do. Both the filter and the swirl pot caked in crap, but also found in the tank some more pieces of blue plastic, now this isnt insulation tape as far as i can tell, but there was a piece stuck to the filter base, another smaller piece in the swirl pot, another piece about inch and a half long stuck in the opening where the return elbow clips onto the bottom of the swirl pot and another small piece floating in the tank near the fuel pump. Anyone have any idea what the plastic could have come from? are the fuel lines lined with a plastic type material or is there a gasket made from that type of product???. One thing i know for sure, if i get it back together, it wont run any worse ;D ;D ;D

Don't recall any blue plastic bits.
Not sure, but when I removed mine I had a helluva job undoing the clips for the swirl pot, so I used little plasic wedges to hold one clip open while I tried to undo the next one. Working round all four. Could your bits of plastic be a previous owners remnants. :-/
-
i will inspect the tank further tomorrow to see if there are any more clues. i used the method you used and opened each clip and then used a small drill bit to act as a wedge then onto the next one. still a bag to do, but looking at all the crap in it, its well worth the effort.

Make sure that the tank base is 'clinically clean' before reassembly. ;)
It's well worth the effort! :y

its still got some diesel in so is there a good way of doing it without removing the tank, naturally i want it as clean as i can cos the prospect of having to take that bloody swirl pot again fills me with dread.

After disconnecting the 'feed' hose I attached a length of suitable hose from there to a barrel, and let the pump empty the tank. Each time you turn the ignition key, the pump runs for about 30 seconds.
After removing the swirl chamber, I used plenty of lint-free cloths to clean the whole tank base.
After reassembly, I replenished the tank by straining the fuel from the barrel using a clean watering can.
Worked a treat thereafter!

well its all back together now but on test drive i cant tell that much diference. it seems to start a bit better and it seems more driveable setting off from junctions so in that way it is better but generally it still seems flat on acceleration till the turbo kicks in. i ahve took offf the plastic part in the engine today which says turbo diesel on it and it looks fairly clean inside, running the engine with that off, the turbo seems to be boosting ok too. at the other end where it connects on ( the egr valve assembly i think) :question it was crusted up all over the spindle from the diaphragm valve, i have scraped off the worst of it but what is best to clean it with and can it be done in situ?? i have also heard of people blanking off the egr connection, where would that be done?? many thanks

You could clan the EGR with brake fluid this will soften the carbon deposits.
You can blank it off, at the exhaust inlet pipe on the EGR. i.e. the shiny rigid pipe.
Flat spot, check that the small braided hose attaching to the under side of the inlet manifold is not blocked or split, tends to occur at the nipple under manifold. :y
