Ok i bought 2walbro 255 in tanks. Now i need some help. IM going to run a KAI BB with all the good stuff. So im going to get steel braided lines but im not sure what sixe. My injecotr setup is 850 primary and 1600 sec. I modifed the stock rails to make those injectors work. For the fuel line i am thinking withor -8 or 10- to a Aeromotive Fuel Filter to the Aeromotive FPR. The return line eithor -8 or -6. The pumps will be in parrelle going to 1 rail. Let me know if my setup sounds ok. TIA

-6 feed is all you need if you run separate lines, -6 return as well.

So what dose the -6 feed max out at? Im going for about 700rwhp when all said and done! By separate lines do you mean 1 -6 to the prim and 1 -6 line to the sec? OR separate as in other than the metal then rubber lines that are there now? Thanks

I think a -6 will max out around 500BHP (not rwhp), but that is with one feed line. When I said -6 will work I was assuming you were going to dedicate one line to each pump/rail and run them separately. If you are going for 700rwhp you may want to run -8 though just to be safe, are those two Walbros going to cut it with that kind of power?

i have heard of the walbros pushing 500rwhp each so 2 should be the job. I think i am going to run a -8 as the feed to one rail and than a -6 as a return.
