Air Filter Minder Inaccurate

Recommended Posts

I just replaced my engine air filter with a new Fleetguard air filter.

I pusher the button on the gauge to reset it. After driving the coach I noticed the filter minder is at 22 about 3/4 of the way to the red portion.

Any thoughts on the problem/resolution would be appreciated.

Thank you,

That is common. I spent 40 years with Cummins in CT and I think they are like idiot lights for oil and water NG. The only accurate way to measure air cleaner restriction is with a manometer or magnetic gauge .

Actually, it is quite possible that the gauge IS accurate. Remember, the gauge is reading TOTAL restriction on the air intake. This includes intake on the side/rear of the coach, ducting to the air filter, air filter condition AND SIZE, and ducting from filter past the air filter minder to the engine intake.

I know that there were some CC's with inadequately- sized air intakes/filters.

Check with one of the CC owners websites and you will find posts on this.

You might check to see if there is a restriction in the duct work between the air intake and the filter. The gauge can be tested with a vacuum gauge pump tester.
