BMW Z4M complete conversion for E85 fuel

[1zpower7]

Hi,
I’m doing E85 fuel conversion to my Z4M and need a complete AN6 fuel line kit.
I have Radium Fuel Rail, but I need the following parts:

- Radium AN6 fuel pressure regulator
- Radium AN6 fuel filter
- Full AN6 fuel lines (including correct length for each line as factory lines)
- Advanced Fuel Dynamics Proflex connections

How can I find the entire list of fuel lines in the car and their length?
Has anyone here made this conversion and can give me all the right information?

pokeybritches is the guy to contact for this.

I remember when I was interested in upgrading fueling the radium fuel stuff from the e46 does not fit the Z4m. The fuel system is different including the fuel pump, fuel feed line to the rail, fuel pressure regulator, etc. You're best bet is to upgrade injectors and use Josh (Pokey) aka Severn Tuning. The stock z4m fuel system can handle e85.

Josh is the tuner of my project.
I don't sure that the stock Z4M fuel system can handle E85 fuel, but I want to upgrade the fuel lines.

This kit is not compatible with the Z4M?

No, the FPR is built into the stock fuel pump system from what I remember which is controlled by the DME. The e46 fuel system is different. The stock fuel system can handle e85 you just need upgraded injectors

I have upgraded injectors and upgraded fuel pump (Walbro 525LPH), is it enough to run 100% E85 fuel safely?

That's more than enough already

Why is it not necessary to replace the fuel pipes in Z4M while in other cars it's required?

Usually people run upgraded lines for more fuel flow for higher horsepower applications. The stock line/pump is more than enough for anything you could possibly throw at this car, it's even overkill. BMW's have been running e85 on stock fueling for years. The only people I would see upgrading fuel lines are people with e46 M3's running horsepower-freaks turbo kits pushing 700- 800+whp

Looking at E46 and E92 M3's, no supercharger kit requires or gets close to needing a fuel line upgrade, just injectors are included in the kits.

My car will have FI soon.
As far as I know, the main reason to upgrade the fuel lines so that they do not melt or damage with this fuel type.

Stock z4m lines are fine to run e85. just be aware youll also need the radium fuel pulse damper. that kit you listed is for e46 m3, and no, its not compatible, unless you mod a lot of stuff...
