Fuel Pump Location

Post  79Puller on Wed 9 Jan 2013 - 13:24

Hope this is the right section to post this in....going from a mechanical pump to a magnaFuel electric pump. My question is where is the best place to mount this ? Should I mount it as close as posible to the fuel cell and anything I should do when installing the system ? Thanks

At or below fuel cell level. Depending on fuel cell size, desired use of car etc, between cell and rear bumper is common. Ideally pump is fed from rear sump bung, so gravity and high G's push fuel to the pump. High performance electric fuel pumps push great, they don't suck real well. They also DONT last worth a damn running without flow of gasoline as the electric motors build a fair amount of heat, and the fuel flow is what cools them.

To add a few thoughts....
* No matter what you try, fuel and the process of fueling is rather dirty. A high volume filter should be placed between the cell outlet and fuel pump.
* Mount, plumb and wire the pump so it is easy to service. Electric pumps are a maintenance item and you will most likely be working on it...at the track in a panic. If you race a lot, carry a spare pump.
* Plumb it per the recommendations of the manufacturer, including the bypass line called for by MagnaFuel.

Depending on how much room you have, another great option is a front mounted cell and a belt driven fuel pump.
Less plumbing....no motor or wires...or switches or relays....and the stuff lasts pretty much for ever.
Just to think about....

Don't forget about venting the fuel cell. Typical rule of thumb I use is to make the fuel cell vent at least the same size, or one size smaller as the cell outlet to the pump... If the vent is too small it will starve the pump

Most electric pumps are "pushers" not "suckers" so preferably mount it somewhere behind the fuel cell.

Does this same theory of mounting it behind the fuel cell apply in a pulling truck as well ? I cannnot mount a fuel cell in the front so a belt driven one is out, although they do sound appealing. Do to the back of the truck being higher shouldnt I mount the pump in the front ? Thanks for all the advise just want to do this right the first go around.

If you are planning to run in reverse ... or maybe your vehicle won't have enough "G" force to slosh the fuel toward the rear.

The pumping section should also be lower than the bottom of the cell.
