Electric Fuel Pump Location on Total Performance Frame

Hi,

I wanted to know your thoughts on what would be the best location to mount an electric fuel pump on Total Performance 23T frame?
I have a gas tank from Ron Pope and the bung for the gas outlet is on the passenger side, on the underside of the gas tank.
Having a mechanical pump is not an option because my motor is a 305 from a late model Chevy C1500 Pickup truck.
Thanks,

How about on the inside frame rail just in front of the kick-up?

Depends on the pump. Most electric pumps are more efficient at pushing fuel than pulling it,so it needs to be located as close to directly beneath the fuel tank so it will get gravity fed. I have my Holley Red mounted on the frame rail directly under the fuel tank.
 
Mine is mounted on the inside of the frame rail just aft of the tranny crossmember on the pax side. The point about it being easy to get to is valid. I've had to change out two Holley blues in the field. I think the problem was I was feeding the pumps directly from the ignition switch with no relay, and they weren't getting enough power and overheated the motors. I added a relay and heavier wiring last year and all seems well now.

The problem is not really the relays, the Holley blue and red pumps are junk on a street driven car. I have sold Holley blue and red pumps for years, and if you have a regularly street driven car it will fail, sooner or later, and most probably sooner. On daily driven cars some won't last 3 months. I have always told people to stay away from them. On a street driven car the best bet is a mechanical pump. If you can not use a mechanical pump an Aeromotive pump will last, the have a nice one for street rods.
 
Yes....if its hooked up directly to a switch with too small a wire...you'll be putting a strain on 12 ga.....its best with 10 ga. and use a universal horn relay kit, they are about 10 bucks I believe...

Definitely....Lee is right....it helps to have it that way...

I can't argue with that, but I bought my Holleys at O'Reilly's and they have replaced them on warranty, so I've only paid for the first one. If (when) this one fails, I'll be looking for something else (Aeromotive will be on the top of my list). Or I may reconsider a mechanical pump. I like being able to pressurize the fuel system before starting the motor (blower). Maybe just my airplane background.
 
My holley red pump is mounted inside the frame under the floor below the seat area. I know some people have had bad luck with blue pumps but i have had one in my Pinto for 18 years. They used to be the only pump. LOL. I tried an Edelbrock pump and it is just as noisy as the holley blue pump. I would stay away from that.
 
The only thing I can suggest is,if you are still in the process of the build,place it in a place that you can reach easily once the car is completed. I burnt my electric fuel pump out on the road,had to get the savage truck out to deliver me and car home,then found that to remove the pump,I had to remove the whole interior to drill a hole through the body to get the screws that attached the pump to the chassis/frame. :winkn: This was due to the fuel pump been mounted to the chassis before the body was finally fitted and no throught of said pump ever needing to replaced. I have learnt a lesson there!!!
 
Thanks for all the replies my friends!!!

Yep, that is correct! A mechanical fuel pump is no option.
The only problem I see in mounting it on the gas tank side of the kickup is that part of the frame has already been drilled
with 6 holes for the coil-over-shock upper bracket. Won't drilling more holes cause that part of the frame to weaken considerably?

What I plan to do is to mount the fuel pump right below the gas tank on the rear cross member of the frame (the part on which the gas tank is sitting).
Regardless of what kind of a pump I mount, this cross members is the highest point on my bucket as I have big 'n little tires on. This will make maintenance of the fuel pump lot easier.
I may not even have to jack the baby up to service the pump.

Thoughts?

I mounted mine in back with the fuel filter up by the firewall cause of not enough space down below by the pump. Ive only got a 5 gallon tank with a blower motor ,not a good idea. I was going to get a 10 gal tank that cost $170 but thought i could just carry a couple gallon fuel cans with me and save the money. Also no fuel gauge which i dont like ,i hate running out of gas. Happened to me a couple times in my rail buggy with same kind of round tank. Good luck

Nice!!!!! Thanks for putting up the pix. (The headlamp posts really look great).

I have a 10-gal tank from Ron Pope.
Yep, the fuel pump looks most accessible for maintenance. I think this is the way to go.
But in my state the Registry rules are a bit tight. So I guess I will have to run hard lines
in and out from the pump. That will be a challenge to my tube-bending skills.

As for the pressure regulator, I was thinking of modifying the fuel pump block-off plate on the motor and mounting it there.
A quick question, where is the battery box mounted?
 
Mine barely fit on the frame rail behind the gas tank. The inlet on the pump needs to be lower than the than the rest of the system so there can't be priming issues.
Here is a photo that may help some.

How bout an intank stock fuelpump with a regulator.
 
I just used the in tank fuel pump on my kids 97 chev truck. I added a fuel pressure regulator
maa-4309_w.jpg
this one and got the pressure down to 8 pounds no problem. I went from 4.3 liter to a 383 stroker.Got it running last night.
