I got a question about how to run my fuel rails. This is going on a vortec 350 with a ramjet intake, with lt1 fuel rails. My plan are to be around 400hp. Can I get away with running the rails in series. I am clueless when it comes to what size line for what. I was thinkin -8 to from the hard line feed to the regulator and then -6 for the return. Will this work? thanks

 

someone has to know this.

 

Series or parallel: http://www.gmhightechperformance.com...third_gen_use/

 

so would it be better to run -8 or -6 I read somewhere that -6 is good for 550hp I think.

 

-6 is probably good depending on system design, but I used -8 supply, -6(stock feed line) return.

 

Well if I run them parallel I will come off the stock line and Y it to each rail, then come of each rail back to the regulator, and back out the return port to the factory return.

 

Sounds good. Should be good with -6 for 400 hp.
