L2800 fuel problems

[marcg]

Hello all.
I am having issues with my tractor not getting fuel from the fuel pump. I recently replaced the ignition switch because I was not getting voltage to the fuel pump and that problem is solved, yet I still cannot get it to start. I took lined loose at injectors as well as at the top of the pump and there is no fuel coming out at all. I am out of ideas and need a little help. I know that its possible fot the pump to go bad but tractor is only 3 yrs old and has about 300 hrs on it. Seems a little premature for that to be an issue. I appreciate any input yall may be able to give.

Which fuel pump do you mean? there are 2. There's the fuel delivery pump (or lift pump) that delivers fuel to the injector pump which in turn delivers fuel to the injectors. Just so there's clarity.

If you have the humidity I'm guessing you have down there, I'm thinking it is stopped up with fungus. Pull the line from the fuel tank to delivery pump, fuel should pour right out like a Clydesdale taking a leak, a good full stream.
If that is good disconnect the output of the delivery pump and see if the pump is indeed pumping (or not).

No guarantees but that's where I'd start. Hoping it only would cost a few feet of fuel line and a bottle of "bio-cide".

I agree with birddogger. Start at the tank and work your way to the pump.

I did indeed check the fuel supply going to pump from fuel tank and it is pouring a very good stream. The lines that I cracked were from the lift pump going to the injectors and there was nothing even trying to come out there. I am not 100% positive on the ignition switch that was installed it was an aftermarket and not a Kubota might be the whole issue was gonna start there and hope its not the lift pump that is out. I will repost if I have any luck thanks.
