Thread: When to use an electric fuel pump?

Tweet

Good info, guys.

I have a tunnel ram set up on my Nova with (2) Edelbrock 500 cfm carbs. Again,street only and I have never had any issues or hints there of.

Now I am looking at going with a small block or big block blown engine in my Ford and really don't want to move over to an electrical pump either. Again, simply street duty with a little smoking the tires here and there.

IMO with aftermarket mech pumps flowing 110 gph or more @ 9# or more there's just no need for an electric pump for a carbed motor on the street.
Of course FI and limited space is another story.
I run a Holley mech. pump on my blown small block with dual Demon 650s and have never had anything close to a fuel delivery issue.

Blown application, I would use an electric pump. Worst thing to happen is a lean condition in a blown motor. My .02
