There are no dumb questions, that is what education is all about. If you take a piece of wire and poke it into the "Pisser" hole while it is running in the water or on the hose it will probably clear it. They get clogged with gunk from the water or dirt dobbler's nest. Make sure it is always running before and after you turn of the water to the hose to protect your engine from water ingestion.I know this is the wrong thread to be asking questions on but I have a non-turbo r12. What does it mean when u hook the hose up to it and the water doesn't come out warm. I let it run for a few minutes an it never warmed up. I'm sry if this is a dumb question but I am new to all this.
