Fuel Pump

smokeyjoe71 · Dec 22, 2021

Had my fuel pump rebuilt, 1971 Ford 4500 industrial tractor. got it put on, bleed all the air out of the lines, everything was getting fuel to it, cranked and ran, but it was running rough, after a couple of minutes the motor died, now its not getting any fuel past the filter. My 1st thought is its stopped up from sitting for a couple of months, just curious anyone else had this happen? And if there might be something else I need to look at. hope I didn't hook something up wrong and tore the pump up, that was very costly.

Changed fuel filter? If so witch filter? How many orings were left over?

What fuel filter do you have? If you used a WIX/NAPA type, with the groove around the inside top of the element, did the gasket by chance get down into that groove instead of up into the housing?

yeah had that happen. that filter needs certain passages closed and certain open for that to work correctly.

I have not changed the fuel filter as of yet. I will get back with yall later today, I am going to start from the tank and move my way through the lines and see were its stopped up, I was just afraid I done some wrong installing the fuel pump.

If fuel isn't coming through the filter after setting a couple months, and you didn't forget to turn the tank valve back on, your fuel system certainly has a problem.

On another note, personally I would have changed the fuel filter, not just bleed the lines, and made sure the fuel flow was good before ever trying to start a freshly rebuilt pump to protect my investment.

OK Let me run through everything I have done, a recap, Got all the air out of the lines and was getting fuel, Tractor cranked right up, but
was running rough, I let it run for maybe 2 minutes and it just died, then I was getting no fuel any were except the line coming out of the
filter to the pump. The 3 bolts that connects the the wheel sprocket to the fuel pump came out, I am pretty sure I had tighten them, I
lined it back up and retighten them, now Everything is getting fuel, tractor is turning over but not firing at all! ugh, did I tear
something up? Were do I go from here? My thoughts are completely take the pump back out see if I may have done some damage, maybe take it
back to were I had it rebuilt and let them look at it.

When you bolted the gear back up was the pin, in the hub, still in place and undamaged?

I am not familiar with the clearance around that gear. Is there room enough that it could have jumped some teeth?
