Electric fuel pump locations.....

[1974dodgecharger]

I need some ideas on where to install a electric fuel pump, might be going that route with the blue holley.  I have a 3/8 line with 1/4 return with fuel evaporator setup currently.

stock tank or fuel cell? you need to mount it close to the tank but lower. I've seen them on the inside of the frame rail before. Mine is in the trunk, but so is my fuel cell, fuel filter, batteries, etc, so that wont help you here.

stock fuel tank....I wanted to try to mount in the hump area where shock top eyelet area is...that's above though tank.

That`s what i would say but , if you read the instructions they are supposed to be gravity fed . You risk burning it up . I have a Mallory but no tail pipes and a sump built into the tank so mounted it low .

[Ghoste]

Yeah, I would mount it lower than the frame kickup.

I mounted mine on the frame in the passenger side wheel well.  It gives me easy access just by pulling off the wheel.

have a pic?

Reason I want to switch to electrical is because the mechanical is lazy if my car is on a hill going up. 

[Ghoste]

Wouldn't it be easier and cheaper to replace the mechanical?

I have a mopar performance and its 200 something bucks at Jegs and Summit...I always stick with them since it been good to me vs others.

then someone suggested electric holley..they run 100 bucks.

[Ghoste]

Hmm, and yet hills are making it run out of fuel?  I'd almost think there is another issue as well.

sorry, no pics because I ended up going back to the high performance mechanical pump.  Like the others have suggested, my problem was elsewhere so the electric pump didn't fix it.  In your case I would start with doublechecking your floats.  I will say that while the electric pump worked fine, it was very noisy and drove me crazy when cruzing around.

That's where I mounted mine...

Myk, do you have a pic you could post for him?  Also, is yours noisy too?  Mine was noisy enough that I could easily hear it over my 3" dual exhaust going through turbo mufflers.

On street cars, I'd take an old shock bushing, cut it in half, and use those under the mounting bolts. This helps insulate some of the racket from the pump so it doesn't sound like a woodpecker in your trunk.

Dude.  I have a stock exhaust and at any, ANY speed the fuel pump is just as loud as the 440 in my engine bay.  I can't find the picture of my pump's home, but it's nothing special-it's just bolted onto the passenger side in the wheel well...

[68charger440]

I tried some home made bushings also which helped some but it was still annoying as hell.  I don't know if the HP mechanical will flow enough for the track yet but for around town it seems fine on my 500 incher!

[mopar0166]

Tricky question, but I ended up putting it across and lower then the sending unit in the tank.  has worked great and no issues so far.  the pump I used had a bracket, all I had to do is drill the holes to mount the filter and pump.

This is silly.

A $40 pump from anywhere will work.

I agree that a $40 pump should work for any stock or near stock motor, so this problem on a hill is probably not related to the fuel pump.  But in my experience on a built motor the stock $40 pump just doesn't cut it.  We don't know enough about this guys particular combo though.

[68charger440]

I should clarify that the $40 pump doesn't cut it at the track.  Just cruising around town the stock pump keeps up fine even in many built motors.

[1974dodgecharger]

I can sit on a hill and it does like to idle it will die out as in fuel starvation.  I have to keep on the gas every so often.

Even the lowest flow mechanical fuel pump should have no problem in that scenario.  My 500" stroker has no problems in situations like that.  Have you rechecked your float levels?  Don't assume that they are still set properly.  Its worth a doublecheck.  Also when is the last time the carb was completely disassembled soaked, cleaned and rebuilt with new gaskets etc?

[Ghoste]

Yeah, the fuel demands would not be real high at idle, there must be some other issue the hill is just illuminating for you.

Actually no a 40 dollar pump first should not be used, don't be so cheap.  second of all, yes you will gain better performance the less the fuel pump will have to work to get fuel up to a motor, thus it needs to be close to the tank and lower then the fill neck or fuel outlet. 

If you like crappy results and just want to piddle down the road then don't worry about what I said. 

Hopefully this doesn't offend anyone but the statements are crazy if you want performance from an electric fuel pump.

Ma Mopar made millions of cars with those cheap $40 pumps, so for a stock application they perform very well and are reliable.  Modified motors are another story, but this thread is about a problem where just idling on a hill the car acts like it is starved for fuel, and not about performance under heavy load. That should not be a problem for any mechanical fuel pump.  The cure for that problem is most likely in the carb and not the fuel pump IMO.
