You thinking that'll fit our fuel rail?

Anyone ever figure this out? I'm looking to pick one up for my E30.

For anyone still interested in this, I am about to pick two of them up. Received an email from Dennis Kirban today and he says the part number for these adjustable regulators is 4037. They run $149.95 a piece.

Just sent an email to Kirban since they don't have #4037 on their site anymore. Hoping they can supply the FPR with a 5/16" nipple for direct factory FPR replacement.

hey i know this is totally old but i have a big need for a better flowing regulator
^and to answer your hopes these guys make one like that.

just sucks that there's no real info on these or if they flow well.
or if it's even rated for e85

Kirban still has #4037 available too -- just email them.
