Anyone care to recommend a RELIABLE, low performance electric fuel pump for a street driven rat with a stock engine and a single carburetor? Don't need a race pump, 4psi is sufficient...it just has to be a good, solid, reliable unit! (No Holley junk!) Carter made good electrics years ago...they still sell 'em? Any other recommendations??? Thanks!
Hack - I'm running a Carter. They make a 5 psi street pump that's a reliable vane type. Used to be able to get them at NAPA, Summit has them also. Mutt
<font color="green"> Hey Hack, How soon do you need it? I have a little Purolator rattler on the 41 and it works fine, except when you are racing and it can't keep the bowl full. Anyway, I am replacing it SOON and you can have it. By the way, I'm replacing it with the previously mentioned Carter. </font>
Hack, The Carter is the way to go although that little Purolator may work OK for you. That's whats on my shoebox. They are more prone to vapor lock but if you mount properly (down low and near the tank) and run yer fuel line uphill you should be ok.
Thanks. I'm going to run a trio of 94's off it -- middle one set up as a primary, outter two kick in as secondaries. I was told I need to dial it down to 4 psi -- is there a regulator you'd recommend to add to the package?
Napa offers a Facet universal style elctric fuel pump that seems to work pretty good. I can't remember the P/N off hand. I think max psi is around 5 (?) or something. I am using one for the flathead and it seems to work real well for that set-up. The fuel pump cost about $35
[ QUOTE ] I was gonna mount the pump in the trunk [/ QUOTE ] I hope "was" is the key word here. Get a leak near the pump and you're liable to find the trunk pumped full of gas. Mount it under the trunk and make some heat shields for it. The ones pictured work well for me. The pump is in standby status at present. A small thought on the Holley street pump - I've been thinking the problem with the Holleys going south on my roadster is low voltage. Been through three of them in 40,000 miles although one was an internal relief valve problem cured with a touch of 600 grit wet/dry. Anyhoo, I measured the voltage at the rear mounted Holley pump and found it in the mid 11 volt range. (Engine not running.) The installation used the same gage wire that was on the pump - 16 gage I think. Installed a mechanical pump anyway and later on installed a constant duty relay with a 10 gage feed wire about a foot long from the main battery supply under the seat and ran 14 gage from the relay to the pump. Voltage at the pump was the same as the battery voltage at the main battery supply terminal. So there's a new Holley pump under the car, standing by for use as a spare, but I'm about to go back to the electric pump and leave the mechanical in place as a backup - with no fuel plumbed to it, but spare lines in the trunk.
Not to hijack you post Hack, but no need to start another thread for this question regarding fuel pumps.... When installing a 6v fuel pump on my stock 8Ba '49 motor, do in need to run a pressure regulator? What is the pressure that I need to get from the pump? 4-5 psi??? thanks HC
of the electric pumps mentioned which one is queitest? I haven't any problems with my Holley but it is anoyingly loud. I'm also using a Holley regulator that does not give a constant pressure reading and occasionaly on startup will buzz loudly for a few seconds. what is up with that? Paul
HC, I would run a pressure regulator on the 8BA. Set to around 2-1/2 to 3 psi off the bat and see how it operates. 5psi is probably going to be too much for the stock carb to handle. 60's style, that buzzing you here is most likely the pump building pressure. Most electric fuel pumps are internally regulated and once the pump builds pressure the noise level will decrease. Actually, the noise level will increase decrease during regular driving based on what the motor consumption and pump output of gas is required. You most likely will never notice it, however. Unless your ride is too quiet! I doubt most here will have that problem.
To feed that ferocious 6cyl I suggest a Black & Decker Aquarium Pump . I have used the carter pump Fuel Pump mentioned, it was super reliable on the last daily driver I used it on. But I think the part# was P4070. Also check egay someone, was selling Holley reds for like $29.00 and Blues for $39.00. I don't like them either but for the price buy a spare.
Hankcash, It really depends on the pressure of the 6V pump you are gonna use. Unless you a SURE that the pressure will not be over say 5 psi at idle, I would put in a regulator. The pressure of any pump will vary based on the flow (gph) it is putting out at the time. Cruisin down the road (useing say 6 gallons of gas per hour) it my be 3 psi but at idle (useing almost 0 gallons per hour) your pressure could be 6 or 7 psi and flood your carb. This is why a regulator is important. Beatnick, Yea P4070. Good catch.
so who makes a quiet electric pump and a regulator that acurately regulates. no the coupe is not quiet but the eclectic whirring of the pump and occasional buzzyness of the regulator are anoying. I can set the regulator to read three pounds and look later and it will be up around five, I reset and next time I look it's at two.. that's where I have it now, with an occasional high of five psi and a low of two.. currently running two Edelbrock 600 cfm carbs. you can see the Holley regulator and Moon gauge at the left of the picture.. (headers STILL aren't back from the coaters) Paul

60's, Depending on the horse power you are putting out and the system pressure you want, you may want to consider Carter's P4600HP or P4601HP. Either way, that Mallory #4207 is as good a pressure regulator as any we have tested. The Holley has some basic design issues which probably causes most of their problems. I wouldn't use it.
fuel pump, hp at prolly 'bout six times Hack's proposed uh, power plant? that works out to let's see,, about 450 horses Paul
60s, I just talked to Carter's pump engineer and he said their P4601HP will flow 50 gph at 6 psi. So with your regulator set a 6 psi it would support at least 500 hp. If you were to set the reg at say 5 psi it would flow even more and support even more hp. Bottom line ... would be safe with their 4601. Hope this helps. One last point. Make sure you are getting AT LEAST 12 volts to the pump. The lower the voltage the lower the flow.
