Iv searched, haven't turned up many specifics. For those of you making big numbers on stock rails, are you just using this adapter and a -6 fuel line or what? http://www.summitracing.com/parts/ru...41oaAsy18P8HAQ
I cant find any of these that adapt to a -8 or -10 and i know a -6 will run out of fuel pretty dang quick. Let me know what you guys are running
the -6 will supply more than you think . if you run a -6 feed and return . with a good pump you can make some good power . we have a aem 380 pump and -6 feeding my brothers 6.0 turbo Silverado on e85 and it holds good to 14 -15 # boost . but needs a second pump beyond that. and we will be adding that soon.
Stock returnless truck rails. I run my feed line into the regulator and then into the rails. My regulator is a -6 AN. Smokes my drag radials from a highway roll.

Well i hope i can smoke them from a highway roll! The truck is a dually so most likely not haha. Will have a build thread soon
Making roughly 900-1000 crank hp on stock return less LS1 rails (smaller than truck) on e85. 1/2 supply and return to the regulator. 1 4303 pump, 160lb injectors.
plumbed like so... -6 will make a ton of power. Not running crazy pressures either. I'm at 43 base. 25+lbs of boost. For the build in your sig on pump gas you'll be fine.
What iv done in the pass was dual feed the factory rail with putting an adaptor on the pressure port on the passenger side of the rail and then put an H block in the lines. With dual 255s and a -6 feed for each pump and factory truck pressure regulator i never had problem. But also only made about 600ish rear wheel. So it prolly wasn't necessary.
