Hey all!

I have been toying around with the idea of throwing in an electric gas pump under the hood. Is this generally a good idea? What have your experiences been?

Also, what are the requirements for my engine? I'm running a 352 with edelbrock 600cfm 4 barrel and edelbrock intake. I already have a pressure regulator installed and its set to somewhere around 5.5 psi if I remember correctly.

Thanks in advance!

 

Electric fuel pumps are pushers, need to be located as close to the fuel tank as possible.

 

The Holley pumps suck. I went through 2 of those, averaging about 1000 miles each. The problem, I think, is that they have no real effective way to cool, which shortens their life significantly on a daily driver - I drive mine year round, no matter what the weather. I wouldn't trust it for anything other than a trailer queen or a drag vehicle - and it may cause me to loose the race so I don't know that I'd trust it for that. The Holley does need to be mounted low so that it is level with or below the outlet.

Then I went to Carter rotary vane. So far it has lasted much longer than both Holley's combined, including 2 1200+ mile round trips. It can be mounted up to something like 2 feet above the top of the tank - read the instructions - which gives you many more options for mounting. It seems to be designed so that the motor sits in a bowl of fuel which does help keep it cool. The Holley would get hot. This only gets warm.

Is it a good idea? It's not really necessary and I say it is neither a good nor a bad idea. If you're having trouble and think that an electric pump will fix it, find the problem before you throw a pump at it.

 

Bought my F250 about a month ago. Had the second electric fuel pump on it that the previous owner had installed. It kept falling on its nose at speed and up hill slow. Rebuilt Carb and cleaned tank, and valves adjusted (all needed). Also set timing and replaced filter. Still had problem. Replaced electric fuel pump with a mechanical pump from O'Reilly's for $39.99. Truck has run great ever since!

My philosophy on older trucks and tractors: If you've got a problem try to stay as close to original design as possible (unless you've a real clear reason for the alteration). Chances are the designing engineers at Ford knew more than you do.

 

That settles it. I'm sticking with the mechanical pump.

Thanks for saving me some money gents! Now to spend it on something useful, like a headliner.

 

That is exactly the right approach.

All too often with old stuff, you get fixes on top of fixes and all that's really needed is to strip all the "fixes" off and put it back to the way it was engineered originally.

If it ran flawlessly off the showroom floor, it can do it again. One simply has to find and resolve any and all problems.
