"So....I would appreciate some insight from somebody, anybody that can or has looked at the air feed system for the slideout seals and how the 110V high pressure feed system ties with the 12V compressor circuit and feed proper pressures to all components. I do not remember how the dual air feed was on the 551."

Hopefully this answers your question.............................
