General Pump YU5221 Trapped Pressure Unloader - 2175 PSI, 53 GPM,
I purchased Repair Kit For GPU5221 General Pump Unloader. Where can I find instructions for installing the kit?
I've had a similar issue. The issue was resolved when I found a small empty product tank. When the solenoid opened for that product to enter the pump, it was empty so it supplied air to the pump. I'd recommend inspecting each and every tank.
Is it common for vacuum dirt to smoke or catch on fire?
Customer said the longer she used the vac the more her car smelled "yucky" like smokey . I unlocked, opened the vac clean out, and pulled out the big rubber dirt bowl; it had about 2 inches of black water above the 2" or 3" of well...
