Fuel System Help

Post by papaduke187 »

Hi all,

I'm setting up an 1982 yamaha xj750 on a msII system, ive got gsxr600 throttle bodies and a pump i got off ebay that puts out 43psi. My issue is that my fuel rail on the throttle body setup i have doesn't have a return line, it has one input for the fuel pump and only outputs for the injectors, with are 19 lb/hr @ ~43 psi. i was wondering what i need to do to make this work. im not quite sure how to plump this in with out a return line, or if i need to, how to install one. i need to pretty much run everything inline because id rather not put alot of holes in my gas tank, which is why im not using an in-tank setup. let me know!
