I see what you meen about the injector. The LT i originally made with a clear plast fuel hose and i have just renewed it so that i was sure there would be no air bobbles...there is nothing to see only clean diesel fuel, especially after the mount of the electrical pump no air can be seen, I checked the banjos for in and outlet and I see the difference as you said but the outlet is with a small hole and like a filter inside. There are new copper gaskets and both banjos...but I will go and check everything again.
I have changed the filter to a "volvo" type because the VW filters recirculates the outlet diesel from the through the filter, and I hoped that this would help, maybe because of air in the filter...You see the LT is born with a ACT engine which is a D24S engine with lower performance....its born with 69HP to 2100 kg of LT! Therefore i will keep trying until it will run....do you any problems with the HP bosch pump or are they just running and running?
Thanks all ready for the help...
