Fuel pump check

Lonnie,
None of the "budget" pumps will feed a Q-Jet like yours. You need a lot of volume at a relatively low pressure to run a Q-Jet, and the budget pumps need a lot of pressure to create volume. A Q-Jet has a very small float bowl, and a relatively small single inlet, for the same CFM as a 4150 series 750 Holley, which has two large float bowls with two relatively large inlets.

Kenny is dead on with the MagnaFuel suggestion.

Honestly, for consistency and longevity, you can't put too big a fuel pump, regulator, and lines on a race car. We've had MagnaFuel's biggest pump and system on the orange 69 Camaro for 6 years. The worst problem we've ever had is a seal in the bottom of the pump after 5 years, including 1 year where the car barely ran. The entire kit to build their best and biggest pump was under $25, and Summit had it in stock.
