The instructions of every electric pump states low and near the tank. The electric pumps push fuel so they like a gravity feed. Many will defy those instructions and mount in engine bay or near starter and claim the pump works fine even though the pump has to draw fuel uphill. Good luck on your choice.

Mine is on the frame right next to the grounding point of the fuel tank sending unit. My relay is in the wheel well in the trunk, close to the relocated battery.

I usually put mine at the tank outlet under the passenger side floor but have one LM with the pump inside the engine compartment in the left rear corner. It's been like that since I bought it and I left it like that. 10 years later and still going strong. Not sure with the e-pumps available today (made in China) that you would get that same results with an e-pump in the engine compartment.

Wish I had a picture but on my 65 Convertible I have it mounted on the PG transmission crossmember. It is pretty isolated there. I can hear it quietly at idle but otherwise I cannot hear it. I've had it there for many years. Seems to work fine. I like Dave's installation. Very clean.

Enjoy the Corvair!

Mine is similar to Monza Dave, but bolted it to the car with rubber "well nuts" for isolation.

I went to a in tank electric fuel pump a really long time ago when it was still carbureted. I got it from Dave Herrin at "The Source". although kind of a hassle to install (draining the tank, removing the fuel level sender ect.), once I got it going, absolutely loved it. When I went to EFI, I never thought of any other way to mount the pump, it had to be in tank! I sent a brand new tank down to Ray Sedman and he modified it to use a standard GM EFI fuel pump and fuel level sender that both mount in the top of the tank, as shown in the picture below.

I usually go behind that little bulkhead in front. It gets a little busy especially if adding a second filter.
When it's not my car I can't always replace a gas tank that may be a little iffy so installing a clear plastic filter to monitor comes into play.
LM and EM are a little different routing into the tunnel. I keep some cast iron 1/8 NPT 90 degree "street elbow" fittings around, I like their smooth bend rather than abrupt 90 with the brass ones.

I did one lately that had a hacked up steel line anyway so I located the pump outside the tunnel on the left side in back, sort of in the throttle swivel area. Then I fabricated a new steel line to go up the back to the front of the engine compartment. Then a new inlet line to go in to the carburetor tee at the front of the engine rather than the rear.

I sort of like them down low in the back like in the transmission mount area but it's a pain to cut into the chassis line and bend up something decent.

I bought a sack of 1 1/4" rubber washers and usually put 2 under any bolt mounting to the chassis.

FCs are the best with a handy bulkhead behind the gas tank.

I come off the fuse block usually on the same circuit that has the heater and install a toggle switch and used Ford inertia switch for safety.

It's a fair amount of time which makes it hard to talk someone out of a faulty mechanical pump sometimes.

I received a PM asking about noise with my setup. Here is my response:


I have no problem with pump noise. The pump is isolated from the bracket with a rubber grommet, but the aluminum bracket is mounted directly to the floor pan. The floor pans are insulated with strips of dynamat for dampening with foil covered insulation over that. I can hear the pump when I turn on the ignition, and it quiets down a bit as it builds pressure. After the car starts it's barely audible and on the road, I don't hear it at all. If I did it again, I'd isolate the bracket a bit from the floor pan -- grommets, rubber washers, well nuts, etc. -- not because noise is a problem, but because it would be good design practice.

The preferred pump is Facet/Purolator 40104 / FEP42SV. Have anyone used Holley 12-426 ?
