Advice on EM electric fuel pump install
Posted by: Nickshu ()
Date: March 02, 2018 05:47AM

I am trying to decide how to install my electric fuel pump on my 64 Spyder. I like the "candy cane" method published in the recent Communique but I am concerned the fuel pump might overheat in this location.

Any thoughts on whether a pump might overheat in the summer when wrapped in foam and installed like this?

Thanks in advance!

Photobucket seems to be having trouble right now. Hopefully the photo will go through soon.

Wrapping it in foam would not be good. Not only due to heat, but due to water entrapment. Water(condensation) and heat are good to start the corrosion process. Corrosion will set in, ruining your pump fairly quickly. Mount the pump using rubber isolators.

That was my concern. I'll go with this installation instead. It breaks my heart to have to cut the body fuel line that I painstakingly removed from my donor car completely intact and installed during my restoration. Oh well.

I think the Fuel going through the pump will cool it as not to over heat.

Nick if you are running a return line, there should be enough fuel moving to cool it. I used a rubber "well nut" where I secured it to the car in order to reduce noise transmission.

I mounted mine on the inside of the passengers subframe. i used the clamp that was included in the kit to install it. You can hear it when you turn the ignitikn on, but not once the engine is started. I have not wrapped the fuel pump and have had no problems.. using Airtex E8016S.

Thinking about it more some people mount these pumps in the engine bay of various cars. They are probably designed for the heat to some degree (no pun intended).

I wouldn't rap it as mentioned above heat and moisture. Also I would run a pre-pump filter. It doesn't take much crud to screw up a electric pump

Wrapping in foam will trap water weather from condensation or water from road spray. Either way, trapped water will start corrosion. If need to wrap it for sound sound deadening, try to find some way to keep air flow between the wrap and the pump to dry the motor.

Nick,
Look at installing an in-tank pump.
It will require the least amount of visible modifications, be quiet, and efficent.

I agree with Ratt, you can hear the pump but as soon as the engine starts the engine sound over powers the pump sound and you don't hear it anymore. I actually like hearing the pump, if you listen close you can tell when the carbs are full, the tone changes and you know it's time to engage the starter.

My favorite place is down low in the back near the crossmember which involves cutting the steel line, sometimes too difficult to deal with when it's rusty.

Next favorite is down low in the front. It gets a little busy with a filter.

I don't like up near the starter as they push better than they pull.

I like reading about and seeing clean installations.

I think I will install just behind the front transverse "I-beam" part of the body where the rubber line meets the hard line just aft of the gas tank. I have a rubber isolator stud so thinking that I will mount this thru the passenger's floor as there is not enough vertical clearance to mount on the "I-beam" with a rubber isolator. Using the Airtex 8016S pump w/ the pre-filter.

I have looked at the in tank pumps yes it's a clean (and complicated) install but it appears they push alot of pressure so you have to deal with that.
