My radium engineering fuel system

Beautiful, clean and does the job.

Where else have you seen the regulator setup in a way that it doesn't need a return from the rails? Love this design

[@shionnsr8684]

Dope set up!!

[@EcFlipz]

I know Radium recommends mounting of the surge tank to be vertical or at 45 deg for best performance. Have you found any issues with the tank being completely horizontal? I really like how it's hidden in the spare wheel well, something I want to consider doing too.

[@Vexman2200]

how do you get a vacuum reference for the regulator in the back?

[@Alex-ez2ym]

great setup and walk through, do you also have a pump inside the tank or are you just running the 044's??

[@SuperchargedJester]

Yes, I'm running an AEM 320lph e85 compatible pump in tank. This keeps the surge tank filled up, then the 044s draw from the surge tank. It works great. The 2nd 044 pump turns on @ ~5psi boost so is not drawing so much current at cruise and idle.

[@EagleKeeper86]

Anyway you could add a surge suppressor from the regulator return? I would be worried about the vibration working loose the B-nut.

[@SuperchargedJester]

Oddly enough it only does it at idle in park, when its cold. I've since put a couple hose dividers on them and it's hardly noticable now.

@@SuperchargedJester I’ve been considering this on my 03 Focus, the fuel pump is located at the front of the tank. If I run any more than 8.5 lbs of boost the pump cavitates. Nice idea using the spare tire well, I can’t remember the last time I’ve had to use my spare, and there’s not a lot of room anywhere else for this setup.

Are you still using stock fuel pump inside the tank to feed into surge tank ? and are you using a fuel pump inside the surge tank that feed the 044 pumps I’m new at this just wanna do my setup right
