New fuel pump= flooding and gas every whare.

Thanks for the suggestion. The good thing about NAPA is they actually have values for pressure and flowrate. Seems like Autozone and oreillys don’t think that’s important.

I don’t want to replace the pump with another one that may have still have excess pressure and get no further forward. I can see how a lot of folks just put on something and let the separate regulator compensate for not having the appropriate pump.

The return line on the installed pump is just capped off, for good or bad. That’s another argument for changing the pump to a 2 line with the lower psi output. Seems like the lower psi (lower flowrate) pumps have 5/16 inverted flare connection, complicating getting to the (probably original) 3/8 inverted flare at the carb.
