Fuel Pump

[D&D72]

Looking for recommendations. External Fuel pump for EFI. who has what and, what are your likes - dislikes? (I'm running an explorer 5.0)

Carter P4070 low pressure pump

Airtex E2000 high pressure pump (cross reference as late 80's truck/Bronco EFI pump)

LP pump has been in only 1 year. I swapped it due to Viperwolf's warning about the LP pump I was running. HP pump has been in 3 years.

I like simplicity. I believe on Shawn Gregg's we just put an e2000 pump close to the tank (low as you can get it). I don't think he has had any problems with it. That's what I would try first. If you have problems then you can invest in a more complicated system.

Cool I see Advance has them in stock. Thanks!

I am using the same set-up as Chad. One thing he did not mention was the accumulator between the 2. I got mine from BC Broncos-- I think Chad made his own. I have not been running mine long enough to truly be able to give a or down.

If the HP pump ONLY is a reliable solution, it saves you a bit of money and means less noise and potential for failure...

I originally installed a frame mounted fuel pump on my EFI install but it wouldn't pull enough fuel pressure to run my engine. I then went to an internal tank fuel pump, it has been running flawlessly ever since. I'm not sure the difference but my experience is but the internal pump has performed better than I expected.

The in tank pumps are known to run cooler, seems to make more of a difference with high pressure pumps.

An in tank pump would be my preference if I had the tank for it. not ready to part with the $$ just yet.

I'm running a Holley Red LP at the tank, and the factory external HP pump from the donor truck (1994 F-250). The red pump makes a bit of noise and it may fail at some point, but it's been that way for 6 years.

No accumulator on mine.

I snagged that pump from a PNP and if ever craps out it'll be super easy to swap out with the 2 back up PnP pumps in my spare parts box. It's nice having the fuel pressure gauge on the fuel rail to make sure it's has pressure (37-40 psi). I videoed the guage while driving up hwy 7 and it held steady at 40.

The first EFI Bronco I saw, the guy put it in the tank himself, got a hole saw and cut the NWMP tank and built it from there.

Here's a tech article on CB where the writer put one in a plastic tank:

Explorer pumps are not too pricey in the 'yards.

I modified fuel tank . Cut 3 inch off top and welded back together also cut hole in top and made baffles in tank for pump . All is well so far , bottom line I have extra inline pump that came with msd injection kit if you are still lookin for pump . Cheers

Old thread sorry, but I know my Holley LP pressure is likely done. So is this Carter pump still the go to? It's half the price the Holley is, and only slightly larger.

I've been using it with no issues.

[D&D72]

I went with the e2000 pump. some time down the road I will likely go with an in tank pump.

Good news Eck!

John - I have the factory HP fuel pump located inside the engine bay. It's less work for me to replace LP pump than to move the HP pump. The downside to that is if the LP pump fails again, the engine cuts out if I try to add any throttle, but at least it still runs... Perhaps I should spend $30+/- and rebuild the Holley as a spare...
