Wondering what the thread size is for the banjo bolts on the VP44 and the fuel filter and the lift pump, i'm assuming there all the same but ya never know...I do know they are metric but can't figure out the size...want to change over to like a scotty fuel system but gonna get everything through a friend that has a small shop here...called him and he said to bring one down..but don't want to take the truck down for that....its on a 99. thanks for any info....

 

12 x 1.5

 

I rethreaded the EARLS steel #EAR 961606ERL 6-AN X 1/4" NPT fitting to a 12mm X 1.5mm in place of the 1/4"NPT and then use regular Cummins banjo O-ring washers.
