You will really like a $40 elec. fuel pump.

Try this but check the pressure on the box but I think this is it. Item 425

Here is one elec pump option: https://www.aircraftspruce.com/catalog/eppages/facetpumps.php
You can rebuild the original for nothing, clean the points and screens, maybe even take out the diaphram and clean the inside of the motor.
There is not much to go wrong with the old SU pumps.
Then again the there are cheap universal pumps available for $40 and even better solid state quite ones for about $60.
When either of these 2 pumps goes bad, you are stuck on the road.
When an SU goes bad, you can fix it with rap of a hammer or big stick you find on the side of the road /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

I have used a few of these. You will note in the pictures that there are two wires leading out (black & red). Since these are best mounted on a rubber mount (electrically and acoustically isolated) you can run the appropriate wire to ground and the other to power.
If the pump only has one wire I have never yet found one that is positive ground.

I have the Facet pump, which I think I got from JC Whitney. I don't think it was even $40; I seem to remember $25. I like it a lot. I might be imagining this, but I felt that the car idles a bit smoother with the electric pump. I can't think of any good, noncontrived reason for this, but it still seems to be the case. (Of course, one reason might be the well-known phenomenon that when you do something successful to a car, it seems to run better. Even cleaning the engine...!)
I think the Facet has no case ground--two wires come out of it. So, you can use it positive or negative ground.
My main concern is reliability. I have never had a good feeling about mechanical fuel pumps, especially since a common failure is a split diaphragm, which creates a path for gasoline to get into the sump. Also, my car has had big-time vapor locking problems, for some reason, and the valves in mechanical pumps do not like fuel bubbles. The electric pump was one part (not the only part) of solving this problem.
