BMW Z4M fuel system upgrade

1zpower7 · 05-21-2022, 03:33 AM

My ///M becomes FI and will run on E85 fuel (I upgraded my fuel pump to WALBRO HELLCAT 525LPH).
I want to upgrade the entire fuel system of my ///M with radium components in order to support it in the best and safest way.
I have already radium s54 fuel rail + fuel flex.
Does anyone have experience with this and can help me choose the right components? (PushLok Hose Ends, DMR, Fuel Pulse Damper and etc...)

whatever you do with pushlok, always use a hoseclamp on those barbs, even though they say it's not needed.

This!! Exactly!

Btw, you need the radium fuel pulse damper otherwise you'll get erratic injection if your running that rail. I have the same setup on mine and I love it. There's also the surge pump from radium that's a good buy, esp.if your running e85. Bit exy, but well worth it.

Thank you for the reply!

1. My fuel lines will be 6AN so I'm guessing I'll need the "FPD-XR, Inline, 6AN" option:

2. Can you provide a link the surge pump from radium? Will it work with WALBRO HELLCAT 525LPH?
