Thread: electic fuel pumps

Tweet

i've been wanting to convert my mustang over to an electric fuel pump for a while now and i'm finally looking at them, i'm considering a holley , but i also saw that mr gasket made a fuel pump for only $29, but i dont want to waste my money if its a piece of junk, anyone ever use the mr gasket electric fuel pump? if so does it last? thanks

Summit has a regulator and pump package for $127.95 part # SUM-G3136K. I bought the same one a couple of years ago for my '66, but never got around to installing it. You will have fun mounting it close to the tank.

I dunno. $ 29 seems too cheap. I've always run Holley red pumps, and the one on my '29 has been on there 12 years. They are a little noisy, but they work really well.

Like I've mentioned before, put a filter BEFORE the pump. They hate dirt.

JMO, Don

It won't be noisy if you mount it in rubber. Go down to Pep Boys and get some muffler hangers, the type that have the large, square black rubber hangers that are drilled with holes. Cut off any metal and just use the rubber to bolt to the car and then bolt the pump to the rubber. Voila, a noiseless pump.

sweet deal! sounds like i'll go with the holley red pump then, i have the tools neccisary to cut the original metal line and put fittings on it to go into the pump too.... should be a nice little addition to my stang... now i just need to get my blasted transmission back in without a tranny jack =/

Awwe Yes!!! The infamous Tranny Press. Much like its cousin the bench press. Only when accomplishing this feat, you are underneath a car instead of in an air conditioned gym and oh yeah....one side is MUCH heavier than the other.

As for the pump, I can only tell you what I believe my luck would be, if I bought the $29.00 pump....not to soon after installing it, I would be left walking somewhere......and then I'd have to go spend the $115.00 at Summit for the Holley Red Pump.

Oh, by the way, use a short piece of rubber line into and out of the pump, otherwise it's still gonna rumble in the car. You have to isolate it completely with rubber.

alright, makes since, it would look cleaner without using rubber hose, but i'd rather not have any rattling... then again you probably cant hear it over my exhaust anyways

if its the one from the chrome isle at autozone,,,it'll only work for a 4cyl....no way will it have enough pressure to run "right" on a mustang,,,itll drive and idle good but if you get on it hard your carb will run out of gas...been there done that with a stock 350 chevy

not the preassure output, you only need 7 psi max to run a normal carb'd motor, some require less. my 200 I6 only needs 4.5 PSI. it's the GPM that make the diffrence with fuel starvation

with the higher pressure and volume, don't let it all go to waste on the stock 5/16" fuel line.......for any kind of performance engine, I would use at least a 3/8" line.....

depending on your motor id say just get a good holley mechanical fuel pump ....but the old electric one i had from autozone was 5 to 7 psi it didnt say what the gph was but it was the 39.99 one and i kept running out of gas,,,,we put a holley fuel pump on it with a regulator and set it at between 7 and 8 with the motor running and it works fine..........YOU GET WHAT YOU PAY FOR!! 9 times out of 10

Make sure you run adequate size wiring to the pump.

If the wire run is fairly long - and it will be if you use an oil pressure safety switch - a constant duty relay will be required.
These relays are available at NAPA, just be sure it's listed as continous use.

Check the voltage at the pump.
If your battery reads 12.2V with engine off and the voltage at the pump is 12.0 and above you should be ok.
Better if pump voltage reads 12.2V.

A long run of small wire (IE: 16 gage) may end up as low as 11.2 - 11.4V at the pump.

Mount the relay not too far from the pump, feed it with a fused 10 gage wire, run a short 14 gage wire to the pump.

A lot of guys just connect the wire and call it good if the pump hums, but pump life will be considerably shortened by low voltage regardless of make.

See if the Mr. Gasket pump compares to the good old AutoPulse pump that's been around forever.

They used to be pretty good pumps and probably still are.
These same pumps are used on Piper low wing aircraft and others.
Although they get an 'Official' aircraft sticker on them and the price goes to $125. or so.

You can find these pumps in the online Spruce Specialties aircraft supply onlline catalog so you can compare.

Hey thesals, a quick and helpfull cure for your Tranny Jack issue. Take Hydraulic jack. Apply large piece of plywood(about 1 inch overhang from each side of transmission pan). Get someone to help you hold the transmission up while sliding hydraulic jack/plywood under transmission. Then, you can roll the thing on the jack to help align. I'm not saying its a perfect cure, but its done it for me more than once

As many times as I've wrestled a tranny in, I've never taken the time to buy a tranny jack, and Harbor Freight runs them on sale for like $ 49.00 all the time.

Next time I'm near one I have got to pick up one of these. Gettin't too old to do the benchpress anymore.
