Thanks for the ideas, my buddy was driving the truck and trailer back from Bakersfield. I wasn't even in the truck with him. As luck would have it, he was hauling two miatas in the enclosed trailer and removed some fuel line from one of the cars. He managed to get back to HB, but said the truck seemed to lack power. Not sure what is going on. I just put in Mel's Baby moose and injectors with a new return line kit. So i was surprised when he said a line had split.
Bud's not a diesel guy so not sure if he really is explaining it the right way to me. He mentioned he tried to start the truck this morning and it didn't want to at first. Then when it did it smoked alot. I asked him what color and he said "grey". I'm going with just loading up on fuel, at least for this morning start up. He did say the egt's never went over 900 and the coolant temp never got hot. he was pulling maybe 8000lbs going over California grapevine.(5 freeway) doing about 35mph.
That seems a little slow to me, but not sure.
Thanks again guys.
