So the o-ring on my single walbro 450 failed for the 4th time the other night. Being that i dont want to deal with it anymore, i am just going to build my own double pumper set up. I was debating on either just doing a full -6 AN feed line or finding fuel hose that can go into a y-block then to the stock feed line. Does anyone know what size hose i would have to use to mate up to the stock feed line? Thanks!

 

Imo just buy a Buschur set up. I built my own and probalby saved $0 . By the time you buy the proper hose ( E85 compatible) , fittings , hardware etc...... it not woth it.

 

I disagree, I built my own and was done exactly as I wanted. Saved $200+.

 

Do you have a write-up you followed or created?

 

I've always looked toward this one, user experience may vary - Fast Freddie's Crack at Double Pumper

 

I looked at pictures of the BR unit, bought 2 fittings from STM for the pump housing, -6AN fuel rail adapter from STM, a 2nd walbro, rewire kit from STM, Hobbs switch from Spoolinup, and fuel line. Basically cut everything off the pump housing and then decide you pump placement. Very simple to build.
