What electric fuel pump on a swapped 4.0 HO (carbed)?

[Yuza]

Hi all, I am running a 4.0 HO in my '79 Cherokee, paired with the stock Carter BBD carb and intake manifold (was a 4.2)
I currently have an electric fuel pump which started making a grinding noise after having run out of fuel a couple of times, probably it sucked some debris from the tank, and I am considering to replace it
What brand/model do you suggest?
Would you recommend a fuel pressure regulator to be added eventually?
Thanks

Holley red fuel pump( there rebuildable too), and add a fuel pressure regulator just to make sure you do not flood the carb floats with to much pressure.

I too used the Holley red fuel pump years ago when I first got our wagon. Did not use a regulator, but probably a good idea.

just my two cents worth,....

I went through several elec. fuel pumps on a 1978 blazer with a newer crate 350

until a red Holley elect pump was installed,....

that was 10 years ago,......it is a dang good pump

it is loud as heck, but reliable.

Thanks all, where can I buy it online (with postage to Italy at a reasonable price)?

summit

or

jeg's

my first guesses.

on last project, I used this edelbrock, it is small and fit neatly against the inner fender, it is wrapped with some plastic so it is not transmitting vibrations , at $60 you can buy 2 and have a back up....

the red one on the right side of the pict or the driver' side of the beep



the fuel pressure for the 6cyl should be 4 to 5 psi, the v8 requires a bit higher at 5 to 6.5psi, I had failing pump and I was running the V8 with 2 psi on a electric fuel pump, of course the engine was not happy at freeway speed


check all the specs on the TSM page 1J9 of the 79 TSM


Edit: as Tim says below, I have used the carter and still have them on 2 beeps, they work well, have a vivration free bracket, ref p4070 IIRC

I gotta a Holley red top on the wag 360 it is loud. It has a pressure gauge that reads around 6psi till the engine bay heats up and I have no return line

Back in the day, the Carter universal rotary vane pumps were popular. They are fairly quiet. The Carter mechanical pumps don't seem to be as high a quality today as they were when cars used them, but the universal pumps may still be a quality part. 5-9 psi is a bit high for a carbureted car, but as above you can add a regulator to get the lower pressure spec'd for the BBD when it was current. Again, these would be available at Summit or Jegs.

Thanks all
TSM says 4to5 psi and 1 pint/30 sec as volume. Is this equivalent to free flow rate?
If so, that is roughly 1lt per minute, all pumps on summit are rated in gph, how do you translate this?

Anyway, 60 bucks is not bad, but adding postage and a fuel pressure regulator (7 psi seems high to me), it becomes a bit expensive

The old lady is currently at the workshop to have a full carb rebuild, let’s see what is the response from the carbs magician about fuel delivery, maybe my pump is still good and just need a cleanup

[letank]

no need for fuel pressure regulator, the pump is self regulating

I have a Red Holley on one truck and a Holley Mighty Mite on the second. They both have been running for 5-6 years now. Look for a carb unit with 5-7 psi. Also, run a ground from the battery with the hot wire to the pump. Land the ground - wire at the pump- and ground both to a clean spot on the frame close to the pump. Nightmare stories related to Electric pumps are often related to bad grounds. Dont forget the power relay for the pump.
