Default Need new fuel pump?

My car is losing power from 2,000 to 3,200 rpm and air fuel is going up to 18.1 during that range. Fuel pressure is dropping to 34 psi.

I am going to try a new fuel pump, what brand and where to get it?

Change your fuel filter first.

Walbro, either the 307 or 340 depending on your needs. Holley pumps are made by Walbro, are plug and play and available through Summit Racing.
