Is there any kind of 12 volt beeper/buzzer that can make a subtle noise every five minutes or so when energized?
I have a 12v fuel transfer pump that pumps fuel from the transfer tank in my pickup bed into the pickup痴 main tank. It is a slow pump and takes about an hour to fill and sometimes I forget it is on and overfill my tank causing minor spills out the vehicle fuel tank cap.
Normally I use this tank and a traditional fill-rite pump to fuel my tractor and equipment but when on long road trips, particularly when towing I use the small pump to extend my pickup痴 range without stopping. I just flip the switch and then have to shut it off before the tank is full.
I was thinking if there was a beeper of some sorts that makes a sound every five minutes or something it would remind me it was on and to shut it off before the tank overfilled.
