I'm tired of my electric pumps giving me fits. I need a 120gph flow at 6psi minimum...Edel only makes them for the 429-460s, Holley has one for the FE buts its about the same as stock, Carter has one but I've had questinable luck with them in the past. Can anybody recomend anything? Thanks.

Let's see ... 120 gallons per hour and say 5 miles per gallon then you've got to be going ... uh ... 600 mph. Lordy, that's got to be one Bad, Bad, Boy your driving!!!!

If it only gets 2 miles per gallon thats still 240 miles per hour and that ain't shabby!

I'm curious, how big is your gas tank(s)?

Why don't you tell us about your truck, car or airplane - whatever you've got this FE engine in; it should make a fun read.

I have a friend that uses stock mechanical pump.I think it was made for an early fe with dual carbs. He runs a modified 428cj in his 4x4 race truck.
This 428cj runs at around 6500-6800rpms and has no trouble with fuel loss.
It is a napa pump but don't have the part #.

I'm gonna guess that his motor doesn't really use 120 gallons in an hour. Rather, its peak fuel demand under full throttle acceleration is a rate of 120 gallons/hour. Of course, you're never fully into the throttle for more than 10-15 seconds at the most. He may well need a pump capable of delivering that rate to feed a motor that gets 6-12 mpg when driven on the street.

Well no, since I removed the Pratt & Whitney engine I had bolted into my bed I rarely do 600 mph. However, I do have a big, bad FE topped by a big, bad Holley. And when I decide to act like an adolescent and light up my 35s in the intersection leaving the fellah in the camaro wondering how he got toasted by an old 3/4 truck I need a pump that will maintain a steady fuel pressure when the hammers down. 120gph is a conservative flow for a "hi-po" pump, several of them run in the 200+ range. So for my type of application and use Karl would be correct that I need a pump capable of 120gph of flow. Stock is something like 65gph I believe. But Karl, I get almost 8 mpg, thank you very much Napa does make a sound pump for the FE but I'm not happy with its numbers. Anybody else?

I'm using a Holley 12-832 7.5psi/60gph and it seemed to be working, I didn't figure that I'd need more than that. The one that I got before that was a Carter and the CAR-M6905 runs at 120gph / 6 psi know as the 'street super pumps' w/anti-float springs, clockable (allows rotation) for $49.95.

I never looked up the flow numbers before but now I'm wondering if I should switch back to the carter.

 

ProSeth, the carters haven't given me trouble but I have an idea or two anyway. How about talking to some circle track racers? I've noticed that carter offers a super street pump mechanical but no race version for the FE. Some of the circle trackers HAVE to run a mechanical pump under their rules. I've seen some mech pumps that have been modified with larger inlet and outlet tubes. Maybe one of their suppliers could beef up a pump for you. If your pump is a bolt together affair rather than the crimped style, how about buying a mech race pump for a big chevy from the manufacturer of your choice and bolting the guts of it to the arm and top housing from the carter ? I don't know if the patterns are the same but it might be worth checking into. How are you feeding the fuel into the holley ? An 8x1 1/4 fuel log would give some extra volume and the pump would have more time to catch up. DF

 

Well shucks, I was hoping for a better story than that.

I too can recommend the Carter. Used it on a built 428 with a 780 Holley and had no problems the drag strip.

120gph is overkill Do you know how much horsepower that can support? if my formula is correct, which is probably isn't but using 1/2lb of fuel per horsepower per hour or .5BSFC, 120 gallon per hour by 6lb per gallon is 720lb a hour, by using a fuel injector lb/horsepower chart that would be around 90lb a hour injectors, or 1300 horsepower so if I'm plotting this right... 120gph is enough to support 1300horsepower, do you need that much fuel?

 

Thanks for the feedback fellahs. The Carter was in the running and that is the one I believe I'll go with. Although
Dino has got me thinking...and since I like to tinker I'll probably end up with a frankenstein. One of my buddy (same one that does all my fab work) circle track races and I didn't even think to talk to him. 'Course, he runs alcohol...hmmm, maybe that can be my next project....

Oh, and sure I need the 'capability' of that much flow. Of course I don't need it on a regular basis, but when I dump the clutch and those four barrels open I swear you can watch the fuel gauge dip. I gotta have a pump that can match my right foot...why risk burning valves with an anemic pump that leans out on demand if you don't have to?
