5411 water pump
I have had an ongoing problem with water flow through the exhaust. It appears I can't hold a prime. Once, the flow started, everything works perfectly. But, If I let it set a week or so, I lose the prime.
Now, I can't get any water out the exhaust at all.
I've changed the impeller, checked the intake filter. Checked the filter o-ring seal, went over all the hoses looking for cracks, poured water down the top of the water pump hoping to get a prime. Nothing works.
How can I find the problem?
