Bike engined mini, fuel pump advice
r1_manx - 1/12/08 at 04:37 PM

Hello everyone,

My friend James and I are currently about 12 months into a home brew, FWD Yamaha R1 mini build (www.r1manx.com and www.flickr.com/r1manx). We are soon to be looking into the fuel system on the car. It will be running an external pump and I was wondering if anyone on here can tell me of a good pump to use in order to serve the minimum pressure requirement of 42+psi on the R1 engine? Any help is greatly appreciated.

Thanks

Ben

Why can't you use an R1 fuel pump or any bike fuel pump over 600cc really would do it? Thought bikes ran at low pressure but high flow rate. 42+psi seems mighty high to me.

Cheers

Thanks for the information, great stuff. I will look into prices on that pump. Did you get your pump second hand? Out of interest, how much did you end up paying?

Cheers

I could use an R1 pump but it's internally mounted inside the fuel tank and I just prefer to run an external pump. I know 40.4psi seems high, that's what the yamaha specs say.
