Air Locked fuel system

[RickO]

I did a real dumb thing two days ago and thought my 2360 was on the last leg. I was milling deep snow. After that, I dropped and angled the rear blade to finish the cleanup. I was in high range, the drive was icy, and I was doing a little slipping as I drove in sharp circles. All of a sudden I lost power, engine killed, and I almost made it back into the garage. I also noticed the fuel pump sounded fainter than normal. After replacing the filter, I discovered a ton of air in the fuel system and can only attest it to having a 1/4 tank, driving fast, and picking up air through the tank outlet. After replacing the filters, cracking the primer outlet, and using the lift pump to prime the injector pump, the engine fired up and ran perfect. If you ever hear a change in the tone of the fuel lift pump, suspect air intrusion.

Isn’t this just the same thing as running ”low” ….or “out of fuel”…?

At least on the BX I don't trust the fuel gauge enough to let it run down to 1/4. If on a incline depending how steep and which way the tractor is heading the gauge will read less or more than on the flats. Similar issue on a side hill. Usually at 1/2 tank based on the gauge when sitting in the garage I consider topping off to full.

Not sure specific for the BX. Maybe not a real issue, but maybe under some conditions it can be. More air in the tank more chance for water vapor to condense into water.
