Default Electric fuel pump on a 79

Guys,

I am installing a Holley Blue fule pump and regulator on my 79. For those of you who have added an electric pump can you please tell me where you mounted it, did you use the existing steel lines? Any advice would be helpful. Right now I am leaning towards mounting it on the frame right behing the rear diff. I do not have the spare tire carrier in place and this location would make the pump lower then the tank.

Thanks, Tony

Your plan sounds about like where I mounted my external walbro and regulator in my 79 C3 ls1 conversion. I used the existing hard line to the engine (with flared couplers at both ends - high press fuel hard line all the way) and ran a rubber fuel return line to tank from the regulator/filter mounted with pump (didn't use the small hard return line on pass side-not needed for the 01 ls1 I used).

I also used the driver side evap hard line for it's intended purpose. Even passed california smog.

Notice that I also made a simple aluminum cover to protect the parts from rocks that might kick up. Under the cover you would see the walbro and regualtor/filter mounted on an aluminum plate (can't find a handy pic right now).

If you havent run one before, you are going to hate that Holley blue pump.
They are VERY loud.
I know you didnt ask for opinions, but if I were you, I would stick with a mechanical pump.

I am/was running a Holley mech fuel pump on mine and it provides plenty of fuel right through 6500 rpm at 6 psi no problem. I am going to convert to FI and am going to run a Walbro pump similar to the setup pictured above. I agree on the Holley electric pump it is noisy.

I had a Holley Blue Pump mounted on the Passenger side Frame near the Muffler. Plenty of Noise to drive You crazy. A 82 FI Pump mounted in the Tank is a Bolt in Option with no engineering to be done at all.

I have run the holley mechanical pump #12-327-11 on my 383 roller motor spinning it to 7500 rpm's with no problems. This motor is making over 580 hp.

As far as the noise of a Blue pump goes, I agree...you may want to consider one of the Mallory pumps (I had a Comp 140 on a Nova SS I used to own, and it was pretty quiet...as long as the engine was running, you couldn't hear it in the car.
