Title: Air system pump filter
Post by: Doug Allman on August 15, 2016, 09:21:09 PM

In our 1991 Contessa on a Gillig chassis the air pump had a filter in the back corner by the 3116 block.  Very hard to see and change and only if you knew it was there.
Does the 2004 Marquis have a similar filter or is it using the regular air filter system for its source?
I have looked and do not see anywhere it could be on the 2004.

Doug,
Your engine driven air compressor uses air from the intake manifold as it's inlet source. Therefore, the engine air filter is for both the engine and compressor.
