howdy yall. Well, i've just had my second electric fuel pump burn out. left me stranded today. It overheated and had to wait an hour for it to cool down, i raced back home, and it died again in my drive way. Anyhoo, i don't know who made the one i had, but it looked like this, cept with out the elcetrical connector (mine was spiced to the wire), and had a clamp that went around it, with one bolt to hold it up (damn thing always vibrated):

this is the second one of these, i had go out on me.

soo, i'm looking for the best fuel pump, as far as quality goes. I don't want to have t replace this damn thing every 3000 miles. if i have to spend over $200 on a fuel pump, then so be it, I WANT THE BEST. the best doesn't nessecarily mean the most expensive either. So i'm looking for the best pump, reguardless of price. and i know those little square cheap pumps suck as well. I had one on the generator on my RV, and it burned out as well.

thanks
-Mike

do you have a bypass setup so it can circulate fuel to cool the pump?

Thu Jul 08, 2010 9:15 am

No i've never of that, how would i go about setting that up? do they have bypass regulators or something? Sorry for the newbish question, but i'm just so used to mechanical fuel pumps. this motor is built on an AS21 fuel injected case (uses a center mount 44IDF tho, 2074cc) so there's no provision for a mechanical pump.

was always wondering about this, but does anyone happen to make an intank pump for carburators? I'd much rather have an intank pump, and modify a stock fuel sender for such. i've heard some good htings about those carter pumps (the skinny long ones). it seems like it woul dbe really easy to modify a GM fuel sender and use that pump instead. Anyone see any problems with doing this?

From a 1980 jeep wagonneer you can get a fuel filter with 2 outlets - one outlet is the big one which goes to the carb. the little outlet you return to the tank.

put the filter close to the carb and at the same height as the float bowl. Idea is the fuel would RATHER go into the carb if it is easy, but if the fuel can't get into the carb, it returns to the tank.

The rotary that CB and Aircooled.net sells are the best I have found for our use. Pressure is right, and they last. Not forever, but years.

Here is SUMMIT Racing version of 4 psi Carter Rotary pump....

I'm using it on race car with dual 44idf and never run short of fuel...

CB Perf. same unit, same pricing...

Trying to put a pump in tank is way to complicated..... stick to external pump designed for use with carbs....

My Holley Red Pump has seen about 10 years of continuous use, but I'm also dialing the pressure way down. It's been a great pump.

If you really want the best you'll need an Aeromotive. I have 2 on mine ---1 for the engine and 1 for the nitrous

Mike, where abouts have you mounted the pump?

This has a huge impact on pump life,
they are pushers not pullers and really need a good steady gravity feed so straight under the tank with as short as possible hose

Also another very overlooked area that kills them is do you have any sort of filter before it?
I know of several pumps that had stopped working due to the rust particles and other small bits of crap that come out of 35+year old tanks and get caught in the impellor

I have this pump, it's been great...

I took one of these off that is 10+ years old with never a hickup... still works great... when installed properly they seem to last well...noisey though

The square Facet ones.. yours is probably good BECAUSE it is over 10 years old. Seems like new ones are variable and sucky like stock mechanicals.

holley.

Thu Jul 08, 2010 7:44 pm

he asked what is the best quality fuel pump possible, not trying to make a piece of shit work a little better by doing goofy unnecessary setups.... JUST BUY A HOLLEY RED, or BLUE fuel pump, with a regulator, they are about $130 for the combo.

Thu Jul 08, 2010 8:05 pm

I had one of those square Facet fuel pumps back in the early 90's. Worked really well in my POS '77 beach mobile DD. I still have the same pump installed in a bus DD a few years ago after sitting in my parts box for 10 years or so, still going strong to this day.

I never had a problem with a Holley Red and a Carter fuel pump I bought from Napa. But then again these are not DD, just weekend cruisers with the occasional run at the strip.

On my next build, I heard nothing but good feedback on Aeromotive fuel pumps, so I may try that next.

Early facet fuel pump,cheap,available anywhere, depenable, easy setup, 20yrs.of offroad use and still working.

Fri Jul 09, 2010 6:07 am

ok let me ask yall this then, what the difference between a red and blue pump? just the color :lol: ? or are there pressure differences or something? Is this regulator a bypass type, to allow gas to circlulate like someone said? if not, should i somehow make a return line set-up? thanks again for the responses.

Fri Jul 09, 2010 6:10 am

also, will this pump be ok for a daily driver?

Fri Jul 09, 2010 6:14 am

just did a search, and:

holley red:
NO regulator
97gph
7psi

holley blue:
W/ regulator
110gph
14PSI

holley red marine:
NO regulator
67gph
5PSI

Mark, that seems to be a big trend these days... newer versions of things going to shit, quality wise.... shame really...

to the Holley pump and regulater reccommendations... not sure I'd recommend those anymore... I've run holley reds and blues, but the regulators that they supply these days are spotty at best... I have one on my turbo engine and it sticks... I am helping a friend with a build(non-vw, American iron) and in the past two weeks he has bought two of the blue with regulator holley setups... one had issues with the pump overheating and shutting off, and both of them the regulators would stick... so, at my recommendation, he bought the red, due to it's 7PSI internal regulation(we wanted 7PSI) and he installed it last night... it has pressure variations from 6-8PSI... May also be a case of what Mark said above, maybe even the old reliables are becoming crap...
