Hi,
I've seen and read lots of threads here on these pumps just can't doesn't seem to answer the question I have.
Tractor ran last year. Started it this year and it had now power. Good bleed on #3 not so much on #1 and #2. Removed the old injectors and pump in new ones. No help, ran a little better, but not much. Decided to pull the pump an rebuild it.
Pump was pretty dirty inside, inlet fuel screen looked like there was no way any fuel was ever going to get through it. Put in lots of new crush washers, o-rings etc but not a lot of actual parts. Clean everything and put it back together. Didn't have the new vane pump parts for that will be here next week.
Anyway I put it all back together, changed the inline fuel filter, had gravity flow all the way to the case bleed ports.
Cranked the engine and got zip. No fuel
Double checked the fuel off to make sure it wasn't stuck in the off position. Removed injector line check valves at the pump to make sure the weren't plugged and checked for any flow from the outlet ports. Nothing.
