kioti lk3054 starves for fuel when it warms up.

There should be a low pressure fuel pump in the system to provide charge pressure to the high pressure injection system. If that pump fails, the injection system will act like there is a restriction on the inlet, ie plugged fuel filter, jelled fuel, etc.

On my old Deere skid loader with a Stanadyne fuel system, the lift pump failed. It would start and run ok for a while, but lose power and the timing would ****** because the internal vane pump in the injection pump couldn’t provide enough suction to lift fuel from the low mounted tank.

A $50 parts store electric pump to replace the old, failed electric lift pump fixed the issue.

Watch the fuel in the filter if the lift pump if weak and failing you will notice a drop in the fuel level in the filter as the engine starts to rev up.

I don't see a low pressure pump in fuel line it's gravity fed. I did check air filter. Also thought about trying a portable fuel tank but I have to pick up some fuel line first. thanks.

also I don't see any fuel drop in filter.

The lift pump bolts to the side of the injector pump. Here is a picture of it on my LK2554.

I will check again tomorrow and try to post a pic if I can't find it. it's dark and -11 f here, lol. really wish I could find the manual, it was my dads tractor. I assume I could test it by blowing into it air should only go 1 way if the diaphragm and check valves are good. Thanks.

there is no lift pump. The tank is set high and fuel line comes out bottom of tank then into fuel filter and straight to into injection pump. I don't even see where one would bolt on, and it always ran fine before, and nobody has worked on it other than me and that was seals in front axle. i'll try to include a pic.

That is strange. The parts breakdown for both LK3054 and LK3054XS show the same fuel pump as mine. Our tanks should be in the same place at same height.

I think someone has removed it. It should mount below your cable. Here is a picture from a view similar to your picture.

I will take a pic a little lower to match yours. My fuel tank is just in front of instrument panel with filler neck right on top between instrument panel and raiseable hood. I will take a pic of that also. My tractor is a lot older than yours, so maybe it the year it was built. maybe I can pull a date off the id tag.
