Thank you

Thanks for the replys, now my next question would you go 1/2 in or 3/8 in?

I know this is a dumb question, on an 02 cummins 5 speed, everything under the hood is stock except for the lift-pump, which is a fass lift-pump, and reading and knowing fuel pressure is everything, how would a big line kit help?

moparman is there any other options for me on the big line question i had last nite, thx danny

what type of lift pump are we talking about and is this an easy thing to do my self, putting the 1/2'' line kit and lift pump in.

hey mopar man, danny here, question on one of these threads i read last nite and i can't find it now, but you and other people were talking about a 1/2 " line from lift pump to the vp44, i just changed mine in nov. 09(vp44) and i checked the pressure, and my numbers were 14 when i bumped it, then when i started it , it fell to about 12, and when i revved it up to 2krpm it fell to 10psi, my question is would running this bigger line help my fuel pressure and save my fuel pump as well, i also put the wally world 2-cycle oil in every fill up, and if you could tell me where the line runs, was it from the lift pump to the fuel pump, i looked on the vulcan web site and saw they had a universal kit for my truck, which is an 02 3/4 ton 5-speed with 117k on it and mine is all factory i don't have anything fancy on it, please help thx danny
