Unless I'm mistaken, I think I need a new pump.
By just applying voltage its connectors, I can hear it work but little to no fuel being sucked. I'm checking this with a seprate fuel gas can (simulate the front tank) and an empty can to see the output side of the pump. No filter in line and only a total of 6 feet of fuel line. I don't have a fuel regulator in play. Just tank, line, pump and the return and delivery lines to an empty tank. I've switch polarities and no change, other than it changes directions from suck to blow.
So I guess I'm in need of one?
If so, where's a good resonable place to buy one?

2 or 3 prong? FI?

Sorry, I forgot to mention it.
Its for an '73 2.0Lt EFI. (3 prong)

A "new" pump? The bad news is they're REALLY expensive. The good news is they're essentially NLA, so it doesn't matter. Rebuilt pumps are extremely questionable, and new Chinese made pumps are essentially expensive fishing sinkers.

The Cap'n

My 73 three prong fuel pump died last year too. Getting a new one was impossible. I converted to the cheaper Bosch two prong and I am not having any problems.

Pelican sells the two prong:

There some Bosch fuel pumps listed on Ebay too.
