    850 Holley With mechanic Or electric pump

    Hi everyone,

    I'm getting a new 850 CFM for my new 502 crate engine, I'm using the same accessories like the combo raw water pump/fuel pump now should I keep using it or is recommended to use a bigger electric one.

    Thank you for you feedback

    I've got a 502/415hp motor with 850 holley. I used the 500HP merc sea pump/fuel pump combo. Works great.

    Stock pump will work well with fairly stock motor. If you up the power over 550 something like this is a good upgrade.
