The pump in the auxiliary gas tank only pumps for a few minutes and then shuts off. After 5-10 minutes it again will pump but only for a short time. I keep only 3 gallons in the auxiliary tank for emergencies only and tried to transfer it today. No way will it pump what is in the tank. Gauge on "E" but no red light yet. Do I have to wait until the red light comes on? Has anyone else experienced this? Thanks,
Ken
