Electric fuel pump mounting

Hello all F-100 guru's,
I pulled the fuel pump on my 65, 352 to check it out and try to remove the frozen on fuel filter canister on the bottom of the pump. I even took it down to NAPA and we were unsuccessful in removing the canister. At that point I decided the pump must be roached like the fuel tank I had to have cleaned out and the gas cap that was frozen and corroded on. All that is taken care of so now I am down to the pump.
I purchased the NAPA electric fuel pump NAPA AUTO PARTS (made in USA) for 69 bucks. The pump has an in-line screw on filter that attaches to the OUT flow. QUESTION where is the best location to mount the electric fuel pump, in the cab back by the tank or under the hood? I bought plenty of extra fuel hose and clamps and have tools to cut the metal fuel line if need be. I also purchased the fuel pump blocking plate for the FE.
Thanks for all your advise.

You want to put it where the instructions say to put it.

For many electric pumps that is as close to the tank as possible with the inlet at or below the bottom of the tank.

I would probably mount it under the cab along the frame rail personally from the way you describe it. Like said follow the directions not all pumps are made the same and don't all require the same installation as each other. Just a thought I'd maybe put a 100 micron or so filter before the pump As a pre filter.

Directions? Oh yea, those! They say to mount it on a frame rail within 12 inches vertical of the fuel tank bottom in an upward direction at 45 degrees from the tank and to keep the temp below 140 degrees? OK. In other words mount it under the cab on a frame rail and not in the engine compartment.
The pump comes with a pre filter on the tank side and I will mount an inline between where the old mechanical pump was bypassed to the carb.

The pump is a Facet Posi-Flo Series 60100, 25 gpm 1.5 to 4 psi. Made in USA. Hope it is a good one.
Should keep the 352 from starving.
Thanks all,

You may also want to put a fuel pressure regulator and gauge on it. You'll want 3 - 4 psi fuel flow. 1.5 - 2 psi would not be enough, based on my (sad) experience.

Sounds like a cool setup. Can't have too many gauges. I like a full instrument panel, you really know what's going on.
I do a lot of woodworking so I was thinking of making a custom gauge cluster from some hardwood. I see a lot of shinny chrome ones but no wood.
Thanks for the advise, I think I will do that.
Have a nice evening.

Since that pump maxes out at 4psi, I wouldn't even bother with a regulator. That's just one more component to possibly fail and a couple more connections to possibly leak. If you really want a gauge, you should be able to find a T fitting for it pretty easily.
