bumble zee Posted March 7, 2003 Share Posted March 7, 2003 dicided to scrap my stock/modded fuel rail... it wasnt holding the upped fuel pressure. So i went to menards and bought some 1 peice 3/8" T's with barbed fittings... and then im gonna run Braided FI hose in between them... think this will do??

SleeperZ Posted March 7, 2003 Share Posted March 7, 2003 Sounds like it should work if you can adapt 3/8" T to a 5/16" fuel injector hose. I spent less than $50 on my fuel rail - 2 feet of stock from AZMarine, 6 1/8" NPT barbs, 2 3/8" NPT fittings for the ends. I just drilled and tapped the ends and 6 injector barbs - voila! Custom fuel rail. Are you sure your old fuel rail was not up to the job? A restrictive rail will not lose fuel pressure, it will gain fuel pressure, as in you can't regulate it well. If you were losing pressure, check your fuel pump. Quote Link to comment Share on other sites More sharing options...
S30Z Bushido Posted March 14, 2003 Share Posted March 14, 2003 excuse my ignorance but what does NPT stad for? i'm interested in fabricating a fuel rail like yours also. do you have any pictures of yours? Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted March 14, 2003 Share Posted March 14, 2003 NPT = National Pipe Thread. They are standard tapered threads typically used in iron pipe plumbing that don't require sealant to seal high pressures. I used teflon tape anyway...I hope it got compressed enough to not get any pieces caught in my injectors, but I ran the pump a while before I fired it up. I didn't take any pictures of construction, but I shall be doing a "shoot" soon to post, so you can see it installed, along with my new 3-1/2" intake and 3" exhaust. Hope it runs as well as I hope!

Jwink25 Posted March 15, 2003 Share Posted March 15, 2003 I was thinking about building a fuel rail as well. But, I am not really sure how to go about it. I was thinking of buying that $12 a foot fuel rail and drilling and tapping for the fittings and everything. But, I have a few questions. Where do I put the fuel regulator? The stock one bolts to the fuel rail, right? Can I unbolt it and just add it right before the new fuel rail? Or, do I put at the end of the fuel rail right before the return line? These might sound like dumb questions but, I am still learning how to hot rod fuel injected cars. I just want to go to battle with as much info as possible.
