Re: Electrictric Fuel Pump - Where to Mount?

That's where I have always mounted mine, on that "kick-up" portion of the floor. IIRC my fuel pressures were about the same, but the AFB's didn't seem to be horribly affected at 5psi. Of course I never went any faster than mid 11's anyway.

At one time I fell victim to "Moore's Law" (if more is good, too much is just right), and had TWO of the Carter pumps plumbed into a 1/2" line. A lot of work and it didn't appear to make any difference. That bare floor was like a sounding board, they startled passengers the first time you started the car.

I did have an issue the first time I used a Holley blue pump, evidently had a small leak or something that allowed the pump to lose it's prime on occasion (It does sit a little higher in the A-Body but still works okay). I ran up to McDonalds to grab a hot fudge Sunday one night during the Frankenmuth Cruise (in essentially my pajamas) and it stalled and would not re-light in the drive-through line. Very embarrassing. I always build 1/2" pickups and attributed it to a pinhole at the flange that I could never find. Only did it once or twice in the few years I ran that configuration but it was always in the back of my mind. And as much as I liked the Carter pumps the Holleys do have rebuild kits available.

My two cents...

I've got a carter electric fuel pump mounted on my '65 Belvedere in the axle housing area behind the outside of the back seat area. This is pretty much even with the stock gas tank - maybe a tad higher. I do want to maintain the stock tank and the space between the frame rails and the gas tank to run the exhaust.

So, the questions are - is the current location okay (not too much suction lift?) and where else have others mounted them on similar cars? It's currently a leaf spring drag car but I see it back on the street in a few years with an engine with a less demanding fuel need.

Did I mention that the Carter needs to be replaced because testing yesterday revealed that the fuel pressure dropped to 4 to 4.5 psi from 7 psi once I went over 5000 RPM.
