hi all, anyone taken a fuel line off the diesal pump on a 3.1td? one of mine is leaking and unfortunatly it was the m.o.t man that found it Crying or Very sad

i am going to try and tighten them up(there are 4 and cant see which one it is with the leak) if i dont stop the leak (or drip) i will have to take the line off and reseat it. the question is ,how do i get rid of the air that will go into the pump if i have to do this? thanks all Very Happy

on closer looking with a mirror and a tortch,with the engine running there seems to be a nut in the middle of the 4 fuel lines(where they conect to the pump) this is what is leaking..........what is it? does it blead the pump? if i unscrew it what type of seal has it got and will it chuck a load of derv out? please help! covered in oil spanner in hand, patiently waiting Very Happy

thats the 12mm dial probe hole. it doesnt have a seal other than the threads. Your pump rear seals probably want doing. difficult to tell the other side off the computer mind you

If it's the bleed, it's supposed to have a copper washer for sealing Wink

do you mean internal seals that are allowing the dev to come through the back of the nut you know ,where it shouldnt be. would it not let air in there? its running lovly but 14mpg which can only be expected Shocked

If you've 4 pipes coming out of the top of the pump in a circle, there's a bolt in the middle. This is the bleed for the pump (it only works with the ignition in position 2 though due to the fuel stop soliniod in the pump. There should be a copper washer behind this screw, but if not, make sure it's tight - there shouldn't be diesel leaking out of it either way Wink

ok i think, the pump on mine has the pipes coming out of the back of it in a curcle and in the centre is a nut??? off set to that is a screw but it is the seal between the nut and and fuel pump housing that is leaking ..........i think anyway coz it is difficalt to see and to get anything to come out of it you have to drive for 5 mins or so. not realy a leak but more of a weep. and thats just me Laughing

For a single nut, it's worth knocking next door and asking for a spanner, what comes around and all that...

hi all, today i have made no progress , well i say no progress but i have found that between 5 neighbours and me ,non of us has the right size socket to get on this bolt arrrrrrrrr . its two bolts in one. in the centre of the large bolt there is a smaller one which is 12mm .the larger one is more than 22mm but not as large as 26mm. i cant get an open ended spanner near it to find out what size it is and the same story with a meshuring gage. do you know how big the biggest nut is? no probs if you dont , i will buy 23,24,25 mm . one of them will fit! this is all to see if the bolt is loose but i have to know if it is before spending money i may not need to. its all very frustrating Evil or Very Mad

i feel like grinding it out (obviously in a calmer state i wouldnt consider this as an option Shocked

)
