cb750 Fuel Petcock replacement single and duel outlet
« on: August 15, 2021, 02:09:53 PM »
Im replacing my fuel petcock on a cb750 (leaking and seized), it had a duel one on it before but one outlet was capped off (not sure why), would it be better to have the duel or single outlet( and will the single fit where the duel was). and is there any info on line routing , any help would be much appreciated

What year is the bike? Which side is the petcock on? What model carbs?

69-74 have a totally different mount set-up then the 75-76 and up. Does your old petcock mount with two screws or on a threaded bung coming off the tank ?

If it's the one with the screws inside the bowl try and find one that comes with two new fibre washers otherwise fuel can leak even when the tap is turned off.
