My tractor isn't running.
I suspect the problem is water in the fuel. The hose that drains water from around the fuel cap clogged up and water was collecting around the fuel cap. Yesterday I used our air compressor (a recent CL purchase) to blow out the drain line which cleared the drain clog.
I then emptied the bowl that contains the fuel filter. The contents of the bowl looked like it had a lot of water. I also drained some of the fuel from the fuel tank by opening the red drain valve shown in the picture. I drained the fuel tank until the fuel looked clear. There was noticeable in sediment when I first started draining the tank.
When I put the fuel filter bowl back on and opened the fuel valve, fuel did not fill up the bowl. Last time I did this operation, opening the valve resulted in fuel filling up the bowl without needing to crank the engine first. This time, fuel did not fill the bowl until I cranked the engine. However, the tractor did not start and the not fully charged battery ran out of juice.
I'm regretting now that I tried to start the tractor with the fuel filter bowl empty. I'm wondering if I sucked air into the fuel lines and now have an air lock. I could have manually filled the fuel filter bowl with diesel before reattaching the bowl. Doing so would have potentially resulted in less air in the lines. Of course, I'm still wondering why the fuel filter bowl did not gravity drain fill up by just opening the fuel valve.
The fuel filter is obviously dirty and needs replacing. I'm going to order a new filter, charge up the battery, and try again.
Our excavating contractor had trouble starting his track loader after he replaced his fuel filter. He said he got air in the lines. He fixed it by unattaching the fuel line to each cylander and getting the air out of each line.
I'm hoping that a charged battery and a new fuel filter will take care of my issue.
