Default new fuel system questions.

hey all,

alright so i know i'm in need of a new fuel system and i already have a 2nd gen lift pump. i was needing some ideas on how to make it.

i know i'll need a fuel regulator and a spacer for the pump, and i was thinking either 3/8 or 1/2'' fuel line.


any pics or input would be great.

The 2nd gen LP supplies too much pressure for the VE to take. You have to regulate it's pressure to something like 15 psi.

I have a low pressure LP from a combine in my truck, so I do not need a regulator. The 2nd gen LP supports more power, but I'm not shooting for too much..

i have a 24v ddrp fass on my truck it work ok i lose fuel psi a little before half throttle, so i think i'm either gonna go with an air dog or an areomotive fuel pump and upgrade to 3/8 fuel line from the tank back,and put a straw in the tank....think it should help keep mine fed,every thing is kinda pricy thoe, so if you want to go semi cheap i'd just get the 24v ddrp fass, it worked great till i really started to crank my pump

ya thats what i think i'm gonna get is the air dog, i gues i don't feel like searching around for all the parts and all that stuff so i thought i would just go with the air dog instead, no offense and congrats to the guys that made the 2nd gen pumps fit.
