Hi all,
First of all, I have a 1975 CB750 with stock Keihin carburetors.
Some of you already know my plight: I want a vacuum petcock as a back up to keep gas out of my crankcase. RJ450 had the excellent idea of using a vacuum/pulse fuel pump like the one on his 650 Nighthawk, along with the stock petcock. All I've seen so far are vacuum/pulse fuel pumps for the Honda Odyssy (4 wheeler), Honda Elite, Ruckus, and Helix scooters, and one for a Briggs and Stratton lawnmower engine.
I plan on mounting it in-line between the petcock and carburetors and running a hose to a sync port on one of the carbs and probably anchoring it to the carburetors somehow.
Will any of these work?
Thanks!
