Hi guys,

Due to the terrible exchange rate here in Australia I am considering installing my own walbro 450 on my 335i and a friends 135i as apposed to Steve from fuel its stage 2 option.

I have trawled though many diy threads on here and n54 post over the past few months but they are quite outdated.

Question... Have any of you successfully installed a walbro 450 and had it running flawlessly for an extended period of time?

If so, what did you use to complete your setup? Hoses, connectors etc.

Thanks guys!

Whatever you do, make sure to use PTFE hose.

I was planning on using the attached e85 rated submersible hose for the outlet from the pump and use 5/16 e85 submersible rated rubber hose from the Venturi to the T.

Or should I consider using the attached hose for both lines?

[jtswole]

That will work.

Be careful. A few members have had trouble with using certain submersible hose. I think it was Gates brand but maybe they'll chime in.

does anyone know if the factory fuel line uses a female quick disconnect 3/8 or 5/16?

thanks

5/16"

I'll be doing my own twin walbro 450 in the next month or so, I'll post up some pictures at some point. Hopefully someone who has already done it will have some pics/advice

Forgive my crude plans, but this is what i think i will do. Let me know what you think guys.

Thanks
