If your fuel pump(s) are brand new, they are Chinese.

I installed one last year from Carquest that wouldn't pump a single drop of fuel straight out of the box. That one was meant to replace the previous Carquest pump that lasted about 300 miles before quitting.

I finally had the "original" (actually an Airtex reman from the 1980s or 90s, I think) glass bowl pump rebuilt. It pumped gas immediately upon installation.

The first Carquest pump's arm was assembled shoddily. The three pieces of steel on the arm were misaligned and only contacted the cam on the very edge of the arm. The second one didn't do squat. The arm was probably not angled correctly or long enough or something.

Since the fuel pump arm moves in such a short arc to pump gas, it's crucial that it is manufactured correctly. I think the new ones don't "throw" far enough to contact the cam fully.

Whatever. Find an original pump on ebay and send it to Then and Now Automotive for rebuild.

The two pumps are the new ones that don't work. The shiny new pump in my hand is the one that didn't pump at all when installed.

You can see the wear pattern on the first pump that failed. Only 1/16" of the pump arm made contact with the cam due to misalignment of the components at the slave labor camp. Last pics are the rebuilt glass bowl pump which works perfectly.
