Rubber stoppers have rotted away on a three way nipple/mechanical apperatus located under the hood. This has allowed an air leak and has allowed the rear of the motor home to drop. I placed new nipples on but after the pressure causes one to blow off. I can possibly get smaller nipples but they may blow off also. Picture
What year and model coach do you have, that kinda looks like a vacuum generator. If you plug the exhaust port of a vacuum generator, it will blow off the other hoses. Vacuum generator leaks air to function.
I have a 87 0red gv 36 ft. Sorry thought my coach would show. I updated profile a few days ago. Rubber nipples were off and 1 was rotten. Should all three be plugged. Thanks
I am plugging all three to see if that corrects the leak in causing the rear of my coach to go down in the rear
