Default Fuel pump question....

thought I might get more responses in this section. https://www.corvetteforum.com/forums...-question.html

I know this topic has been beat to death. I have read until my brain hurts. Any help is much appreciated.

I would like to just be able to swap pumps and be done if that's possible. Im not shooting for mega horsepower here. 500-550 to the wheels is it. The 255lph pump isn't keeping up.

Thanks.

Maybe try a Kenne Bell boost-a-pump on the stock pump? It increases voltage to the fuel pump, but I believe it's only at WOT/open loop. Many people have used them with success. Best of luck to you.

The boost a pump is usually used in supercharged applications where a Hobbs switch turns on the boost a pump while under boost. If your horse power goal is normally aspirated you should install a higher capacity pump. The boost a pump raises the voltage to the fuel pump, you do not want it on all the time.
