Hi,
I have an L3130 that has about 900 hours on it. Before I start pulling (and replacing) lines etc, I thought I would get some input.
The machine has run wonderfully for the last ten plus years I have owned it but the other day it lost power and died. I towed it back to the barn. Checked the filter and noticed some long fibrous material in the bottom of the bowl. The filter was spotless. Pulled the return line off the top and blew it through to the tank. Put new filter back in (correctly) and started it up and limped into the barn. Next day I checked for leaks and Fuel level. All good. Started fine. Ran at speed so I tried to drive it a little. After about two minutes, same thing lost power and died. Looked at the fuel filter bowl and the fuel level was half way up the bowl. Leaving it sit for a couple minutes, the Fuel level rose. Started at idle and open the bleed. When I did that, Fuel level in the bowl dropped (I would expect the opposite). So, not sure what is going on. All things being equal, why would opening the bleed introduce air backward into the system?
My first suspicion is a large contaminate in the tank(sabotage, mischief). I run only highway low sulphur Fuel with additives in my tank and use a screened funnel every time I fill. I do not keep it full however and it does sit for periods of time. Fuel looks okay in the filter bowl other than long dark fibers.
I have read the other posts similar to mine and believe this not to be mechanical since it will run for a little while.
Although I am 10 hours over on an oil change, I am pretty fastidious about Maintenance, service regularly and keep it in the barn when not in use.
