Re: New fuel pump= flooding and gas every whare.

That AMF0001 looks like a great candidate. Thanks for finding that. Although Autozone says it doesn’t match the ‘81 g30 350 engine I have in the ‘68 C10.

I’m going to go with regulator approach. It should eliminate the risk of a the rated pump value not being accurate. If the new 3 line pump already on the truck prematurely dies then I’ll try the AMF0001. After shutting down the engine, the pressure quickly drops to about 6psi so I think that’s the limit for my carb.

That 5.5psi at NAPA did have a different lever, so was a non-starter (see picture).
