the 99 i have had a leaky shutoff valve for the slide seal and a broken pressure gauge. so i replaced the regulator, shutoff valve and pressure gauge and added in the vacuum pump while i was at it.
one thing to note, is to preset the regulator pressure before installing and using coach air. otherwise it maybe set way to high and blow your slide seal. i use a cap on one end and a air chuck port on the other temporarily and set it with my shop air. i set it at 21 psi.
i used vacuum line and a dot fitting in the solenoid valve like before. i use a female blade connector that i pinch down and then tape in to go over the pins on the vacuum pump.
worked like a charm
i took pictures of the part numbers as well.
