Re: Help me eliminate strong fuel vapors in garage

All I can say is good luck. When I put the 292 in mine in place of the 250 I figured I'd replace the pump just because. That was a mistake. The new pump would flood the carburetor out. When I checked the pressure it was running 7 1/2 at idle and more like 9 at higher RPM. Max fuel pressure on these 6s is either 3 or 3 1/2 I forget which. I returned that pump & used the old one off my 250.
