(1) My Zero Turn Kubota 2 cyl has two inline filters. Replace the one close to the fuel tank FIRST.
(2) I have had problems with the fuel line clogged in the tank.
(3) I installed a brass 'T' fitting on the engine side fuel line after the second filter
(4) On the engine side of the 'T' I placed a brass shut off valve and a hose barb
(5) I put a hose barb on the tank side of the 'T' and connected the fuel line and secured all the fuel lines with small hose clamps
(6 )The third hole of the 'T' I simply plugged with a brass plug
(7) I turned the shut off valve 'OFF' unplugged the third side.
(8) Removed the fuel cap
(9) blew air from my air compressor into the "T" until air can be heard blowing out the fuel tank
(10) Plug the third 'T' hole
(11) Turn the fuel shut off valve 'ON'
(12) put fuel tank cap on
This will unclog the line or tank., If it was clogged.
What ever clogged the line will still be in the tank and may clog the line again.
You can ,now, easily repeat clearing the line to avoid replacing the filters or ("UGG") removing the tank
I looked inside my empty 5 gallon fuel containers and found quite a bit of "MUNG" on the bottom that I mostly removed. Who Knows?)
