OK, as you may know my '72 has a bottom outlet on pass side, and so I mounted the filter then the pump to the rear frame rail just to the rear of the tank, and going across the car....with a hose around the pump for noise, and a hose clamp to the frame....the lines are super easy routing, and I put the injection rated filter on the INPUT end of the pump, thus keeping the pump cleaner also...
I am now toying with the idea of putting the regulator in the rear of the car...
and using the return line as a vacuum source line, there is a reason for my madness, and I think it will work fine if I do that....I am trying to eliminate fuel temp rise in the tank in the summer time, as fumes get crazy sometimes, and if the tank was full, it can keep that float ball in the fuel/fume seperator in the seated/closed position and create a positive pressure in the tank, noticed when pulling the cap off, the fumes/air blow out at me...only one thing can cause that....blocked evap emissions line...and the only thing on my car that can cause that is the valve, and the only way that valve sticks closed is increasing fuel temps in the tank under right conditions....
I also need to come up with some sort of fuel slosh restrictor/reservoir....
frankly I"m wondering if there is a way to make a fast enough acting electronic voltage regulator which can increase/decrease the voltage/power to the pump instead of the Bosch style regulator, thus eliminating any return line at all to the tank, this would make the amount of fuel constantly circulating through the system much less, as if a carb was on the line up front....
ive mounted mine in both spots,first like gene did,but it was too loud for me,so i mounted a 89 vette pump on my existing sending unit and ran the wires down through the top,so its side the tank .But if you have a quiet pump then mount it like gene said.
Pick yourself up a 82 sending unit and mount a late model 90 vette or F-body pump on it. I have a source for the fuel pump electrical plug if you need it.

Re: Fuel injection guys ---- (toyvet1)
Mounting in the tank is not an option. The fuel injection kit already came with a very nice pump and I will not spend money on another when I already have a good pump.
I was eying the area under the tank. On my 1980 there looks to be just one big bar holding the tank up in place. It runs from frame rail to frame rail, under the tank. It's where my spare tire upper tub was pop riveted too.
It's up pretty high, but I wonder if it's still too exposed? I looked at the frame rail on the passenger side, but that puts it close to the exhaust pipe.
I mounted mine on the pass frame rail. There's already a rubber line there and I hard plumbed everything on the pressure side. Just remember that the pump likes to be below the fuel level and likes to push more than pull :thumbs:
Hopefully this isn't too much of a thread hijack...

I would be interested in some more details, I need to make a decision on my tank soon. From Zwede's experience, I'm worried about lack of baffels in the tank, and sucking up air. I checked with Rock Valley today about one of their tanks, and well $$$$ :eek: .
So does you '73 have the same oval shaped cap on the tank, where the vapor lines, supply and return lines terminate? Do you have any photos of you install?
Also does the 81-82 unit mentioned fit into a '75 tank? Anyone know?
I put in a pump with in a self-contained reservoir
from a 1990 Ford Bronco...that's because I have a bronco and knew what it looked like. It puts out 45 psig and 33 gph. There are other vehicles that come in self contained reservoirs also. The Bronco pump fuel supply and return both go into the reservoir. As I understand it is designed as such to support 4-wheeling activities but I haven't had any stumbles like I used to have with an external pump I used to run with a Pro-Jection. I had to fabricate the support assembly and make the large hole on top of my 68 gas tank a little bit bigger...that wasn't too hard. I used the old fuel supply line as the return line and used braided steel hose for supply all the way forward.
The NAPA website is a good place to look for fuel pump capacities and designs/styles.
