Hi all

Not new to dubs or automobiles by any means, I know my mk3's inside out aba's inside out and vr's inside out   I also know my air-cooled's inside out


However im new to this whole idi deal and i have a small problem I have made for my self


I replaced the return fuel lines that run in series from all 4 of the injectors back to the injection pump (I was replacing all the vacuum lines as they were toast and those lines looked slightly cracked and very spongy so I replaced them at the same time).   However I got air in the system,  it ran fine for about a week, however now there is WAY TOO much air in the system.  I did a little trouble shooting and the lines I put on definitely seal fine and I don't notice any other possible leaks but I could be wrong.  

The air is visible in the supply and return line and I cannot find a DIY online on how to bleed it.   nor does my trusty bently manual have instructions as to how to bleed the air out.  I doubt that all this air got in from those lines being off for that little time and never run, but I'm not totally sure as to how these injection pumps work.


I've came across a couple posts (bout 2)  that have said that it "works it self out"   but with VW's I've found that's rarely the case.


Sorry if that's long winded I know you want as much detail as you can get, any input would be much appreciated,  and as per vortex a pic or two for your click;

Remove the feed line from the filter and hook it up to a bucket of clean diesel. If you still have air then it's a problem with the pump/lines, if not then you need to trace the lines backwards

does that mean that it is indeed a self bleeding system?


And if so that canister on the passanger fender behind the intake box that has the feed lines pass through it and the return line cotterpinned to the top is the fuel filter?
