Mine is toast, looking for a replacement.
Couple of options...
1. Rebuild kit from http://www.then-now.com/
2. Replacement pump from Autozone withOUT the vacuum unit...so you would have to do something about the wipers like go to electric...part number is 6510...last I checked it was $27.99.
3. You can modify a cheap small block mopar pump to do the same as the stock pump withOUT the vacuum unit...heres how:

You can try the mil surplus guys...not sure that they have any...wouldnt pay for an NOS one and think it would work...if you can find one even. I would bet it would need rebuilt quickly.
Thank you for the reply and options. I'm going to order the rebuild kit unless somebody thinks one of the other options is a better avenue of repair.
Update:
I got the Autozone replacement pump.
When I removed the original pump I found the spring had broken. I discovered a couple of pieces stuck to the pump and in the block cavity, but where did the rest go/end up and what trouble could it have caused?
I think it would be stuck in the bottom of the timing cover...unless it could snake through the little drain to the oil pan...
I'm moving this to the Stock forum. Useful for rebuild kit info and wiper pump alternative as well as the lost parts tech!
Be sure to tell us where the missing parts turn up, Krek! ;)
I still can't get it to run off the tank. I can add fuel to the carb (or carb cleaner) and it will run until it goes dry. As an added bonus it runs without any (new) unusual noises.
My father-in-law is coming over tomorrow night to help me disassemble the carb, he thinks the needle valve is clogged. Sound logical?
After that I need to find out why it is suddenly leaking coolant from the upper radiator hose (thermostat?) and then I can start chasing the bits of fuel pump spring.
Are you talking about the little spring that goes on the arm? Mine was long gone when I rebuilt the fuel pump and the pump had been bypassed for at least 15 years. Either someone fished on the spring way back when, it found a happy place to live in my engine for those 15 years, or it never had one to begin with.
Have you checked the fuel flow out of the pump? If you don't have a pressure gauge grab one of those cheesey clear fuel filters and at least you'll be able to tell if the fuel is moving.
My new Autozone fuel pump isn't getting the job done either.
Does someone make an 24v electric fuel pump or is there a way to use a 12v pump?
Napa has 24v pumps if you want to go that route. I think you'd be better off just rebuilding the stock pump though. Cheap and easy.
The arm in my original fuel pump has way too much play (side to side). It looks like the holes where it pivots got reamed out after the spring broke.
Autozone replaced the defective pump and it runs fine... for now. ;)
Thanksfor that update!
