Today for about an hour I couldn't get the low fuel light to go off on my SMC controller. Finally, it went out after driving around for a few minutes. It works fine now. Anybody else have this problem?
James, the float could have been stuck under the wires inside the bottle.
If it happens again, look inside the bottle and see if this is the case.
If so, use a long handle screwdriver or whatever to move the wires out of the way. Been there, done that.
