I know this is not the best system and leaks are common. Mine has always worked fine until recently.
Air is leaking off. I have traced it back to what appears to be a pressure releife valve at the pump.
Not the exhaust solenoid. Anyway does anyone know where to get one of these?

Thanks, Jerry.

The only way I have been able to find parts for mine is to go to a large Merc Dealer and have the look it up by the year of the motor.. Sounds strange but I watched them look it up and the only way was to start with the year motor.

Be prepared for sticker shock. The one on mine is bad and I have never replaced it because I refuse to give those crooks that amount of $$.

You might want to search on here - you'll find it.
