Gt 2550 Fuel Issue
 

Good afternoon all. I have been dealing with an issue on my 2005 gt 2550 with a kohler ch23 engine. i bought this machine used last year and have been working out the bugs. The issue i am having is the fuel pump runs out fuel. I have taken off the fuel tank cleaned it drilled out the nipple and all new fuel line. I have the insulation on the fuel line where it comes up to the fuel pump. Replaced the valve cover fuel pump with a genuine kohler pump, and new fuel cap. I can run for about an hour or so and it basically runs out of fuel. I take the line off the fuel pump and it lower it to the ground and gas eventually runs out so no blockage i assume. Once i get fuel back to the pump it will start and run sometimes it stalls again and i have to repeat taking off the line. Any advice would be greatly appreciated as i can not think of what i am missing. Thank you!

There are two nipples.... in the tank and on the pump that is.

Check that the vent in your fuel cap is not clogged.
(you can try mowing with the cap slightly loose to confirm)

I have tried running with the cap loose and it does the same thing.

Are the hoses connected correctly?

Hose are on correct i double checked

Filter on correct, or the correct one?

i had a generic filter on and it was flowing correctly, i switched to a smaller briggs and stratton filter because i read that it had less restriction.

I would think there may be an issue with the carb needle, or float set too high.

Would the float being set to high cause the fuel pump to be empty? when it stalls there is no fuel coming out of the pump until i take off the lower line and get it flowing again
