Well I've only put about 600 miles on it and already my FMU stopped working. I was driving home last night around 2:00. I got about 2 blocks from my house and noticed that the FMU was making a sort of gargling-sputtering noise. I pulled over right away and shut off the car and popped the hood (turbo timer still going). It continued to sputter for a few more seconds then went quiet. I haven't looked at it real closely to see and cracks or breaks but it looked normal when I gave it a once over.

Any suggestions on what to try? Anyone know who makes the pump, maybe I could just swap that out? I highly doubt Mike would warranty this (I'm not his favorite customer at the moment) and I'd rather avoid the hassle of waiting 2 months to get a new one. Can I just say f*** it and buy the RSX injectors or would that be too rich with no return setup?

It's the VORTECH fmu, and that sucks how it went out already. Is the car still working? Wow. And you really need to switch to return-style fuel system to safely use bigger injectors (if they fit) and adjustable fuel regulator.

From my experience I have never known a FMU make noises. FMU is just designed to increase pressure in the fuel system. It's the job of the fuel pump (Inline fuel pump for you possibly) to pump the fuel into the combustion chamber.

Well that's good to know, but alot of members are saying it's making noise and people say it's supposed to do that? I doubt it.

lol thats cause everyones confused. the FMU doesnt make a sound. ITS NOT Powered . it doesnt turn off and on. its powered by Vaccum pressure .

The part that Hums Is the fuel Pump. i bet that just took a **** on you.
I even bet theres a manufacturers warranty on it too.

I feel stupid, I meant the inline fuel pump too, just wrote fmu.

I couldn't find anything on who makes it though. Anyone know?

Wow. Your fuel pump died already? That's almost worse. Is it an SF or OEM part?

It's the one that came with the SF kit.

Wow, top quality stuff. So if I took it to a local shop they could probably find me something more reliable and that would fit correct? Anyone know what flow rate I should look for?

my fuel pump went out the other day too..........i turned my boost down as much as i could and i take it easy on the throttle. Anybody know any websites to go to to order a new fuel pump since i can't get ahold of the f.ucks at SF.

I sold the MSD inline pumps to Player and Nelly. PM one of them for install details today or tomorrow.

But can that one be used with SF's fuel system, i'm not planing on doing a return system...

It is an inline pump just like SF's is.

Thanks again Jeff.

Venom makea s fuel pump for our cars
part # HP 710 310 about $200,00
They also make FMU Venom 400 about $350.00 but it advances the timing (not good for turbo set up)

Good luck
