i need help on a tractor injection pump ...i had some small leaks and removed pump to replace all light gaskets i could without diving into pump , before i removed it it was pumping fine .
so after installation just like it was it wouldnt start tractor . i bled all line and did everything i have done for past 20 years . when i opened the bleeder screw and turned it over to bleed it used to spray out 3 feet ...now it was just drizzling out ...
removed all fuel lines to make sure i was getting fuel all good . then a mechanic said it was hooked up wrong . that the fuel filter assembly was pushing fuel to 2 separate ports the pump end and the middle of the pump labeled #3 ...so he bypassed the fuel out in #1 and said that #3 was an over flow and shouldnt be hooked to the pump ...tractor started right up

its been hooked this way for years and ran and all pics i see on web is like mine , i think there is something wrong or something small not working please help

Have you tried pull starting the tractor? Much easier to purge air from system that way without heating starter.
