Hello out there, I have an L2050 4wd. When under load and the motor heats up the tractor bogs down and stops. I just exchanged the air filter and it still bogs down. I will work on the fuel filter when the motor cools down. Question, can I put a shut off vavle on the hose from the fuel tank to the filter. Kubota forgot this when I bought the unit back in 1990. I hate draining the tank every time I need to change the filter. By the way, am I on the right track to fixing my problem?
