Recommended Fuel Pump or stock replacement

Unread postby wwhite » Fri Oct 11, 2019 10:49 am

My truck has dual tanks, front tank gets filled up when running rear tank, from what I know it is the problem with the front tank.

Truck is a daily driver, driven hard, currently modifications are long tube headers, Eddie intake, custom cam.
Future, next upgrades will be injectors and heads.

Since I am going to be replacing the front fuel pump, what are the recommendations for a replacement?
Also, having dual tanks, do I replace both pumps with the same, or install one high performance pump in front tank?

I personally like the stealth 340 type pumps. They are ultra quiet. I run a Kemso 340 lph that I got on ebay for like 30$. I replaced the previous one I had that had no issues even after 3 years of e85 use and sitting all winter in e85. I changed it just because. I make well over 500hp with those pumps. If you want to go name brand aeromotove stealth 340.

No need in all that just a stock replacement is fine.

You can rig up a transfer pump or run a return line to the 2nd tank and put some kind of selector valve on it if you wanted to.

If it were my truck I would rewrite an unused output pin to control the rear pump and do a dual fuel setup with either premium or e85. That is after you do some mods to her.

Simply write the 1st tank pump to shut off and the 2nd tanks pump to come on up top. Put a couple second delay in there to make sure the regular fuel is out the line for safety. That way you can put better grade fuel or even e85 in the back and only burn it when you need it. But still have regular grade in the front for normal driving.

Great info, next question:
Stock fuel regulator, change it to an adjustable so I have control, or leave it stock?
With different injectors, I would assume I would need a different regulator?

A smaller more suitable fuel pump is always better than too big of a pump.

A 340lph pump will support 950hp. That will kill power by heating up fuel for no reason and will also require a larger return line.

I didnt think about the heat issue. Other than my turbo mustang, ive never experienced any fuel heat issues in all the cars I run them in.. (That I know of) Ive been using them in my daily drivers for years. I run a fuel radiator/cooler in my mustang so I dont experience fuel overheating/boiling. Its the only car I have ever had fuel temp issues. I attributed the fuel temps to all the extra heat in the engine compartment from the turbo, down pipe, forward facing exhaust, unvented cowl hood and my poor routing choice for the braided fuel lines (being moved this winter). When I had a blower making a lot less power I never had an issue which is why i came to that conclusion. I am still running the stock lines too which probably adds to the heat. I wonder if when I upgrade my fuel lines and fuel rails if the issue gets better and I dont need the cooler.
