Default Has anyone built their own stage 2 LPFP? - 09-12-2016, 12:14 PM

Hey Guys,

Has anyone done a rebuild of their stock LPFP to turn it into a Stage 2 pump? It doesn't seem like its should be that hard to me, but looking to tap into the infinite knowledge of the forum.

+1 for same question. Seems Steve from Fuel-It made the first upgraded F30 LPFP with a Walbro 450 on a bench just to test a proof of concept and that grew into the line they sell now? Original thread here: http://www.n54tech.com/forums/showthread.php?t=24382

Would be cool to know if this is something easy to do on your own if you were so inclined and save a few hundred bucks.

Anything special to it? Or was it pretty easy?

Make sure to use PTFE fuel hose. I used radium engineerings 3/8" fuel hose. you will need 2 of these as you only get a 1 ft piece. I used a brass 3/8" double sided barb to connect 2 1 ft strands. Pretty much once you put it on and test it out, if it doesn't leak then, it won't leak. PTFE doesn't deteriorate, get soft or get kinked...
There is actually quite a lot of things you can mess up. I already got a few PM's asking about how to do it. I'll see if someone wants to do one/ take pics and i can give you instructions/a list of things you'd need.
Oh btw I have a 535i, my venturi is built in, yours is a little different but it's easy to rig up.
