electric fuel pumps
 

i have a mild camshaft 502 with a holley 850 on it


curious what size pump i need to go with! holley says to use the blue pump cause it will suppose a bigblock and that the red is more for a small block black is too much for my set up i think!!!


let me know the thoughts

Check out the mallory marine pumps, they make them in a few different sizes. And yes a Holley blue will feed a 502
