Engine/Transmission (1994 - 1998) big line fuel kit need

[Swineheart]

I am looking at the next level of mods to my truck. When I put in a fuel plate and install twin turbos. Will I need a big line fuel kit to turn my truck up to 400HP or is it not needed?

I think factory lines are good for more hp than that. Someone else may chime in and verify.

I dynoed 542hp with the stock fuel system. The stock system will do 500hp no problem.



Then I ran 1/2" line from the tank to LP and it did fine. Now I run that plus I removed all the stock fuel lines and put 1/2" lines to the pump and put a 2 micron filter in between the LP and inj. pump. I also have a fuel/water sep. filter before the LP.



I could feel an improvement by going with 1/2" lines all the way to the inj. pump by my sop meter. Oo.
