Default V3 doesnt run long

Hey yall,

Been a while but still jump in to read from time to time. I had a pressure switch fail on me. Got it finally replaced but now my system only runs for about 10min of driving and then the light turns off. I don't have a pressure gauge but never had an issue before. Any insight?

Could be many things. I definitely suggest first step is to get a pressure gauge. I would be lost without mine.

Make sure your tank vent isn't clogged.

Sounds like a plugged filter or prefilter to me. Pressure gage would help immensely. When was the last time you you changed your filter. Could also be a worn pump that when it warms up it can't maintain pressure. Answer back and we will get this worked out
