Fuel needs

On an engine dyno. And, no. It's not going lean, but Holley tells me I'm leaving power on the table if I'm under 6PSI. I've seen a Valiant pick up 3 tenths after the dude adjusted his regulator. Granted, was running a Dominator, but still.....3 tenths from 4PSI to 7.

I think I found the Carter pump. One was discontinued and another part number took it's place.
