Filiter Minder Pegs in Red

Filter minders are pretty simple spring activated devices... not likely to malfunction. Does yours show how high a reading it goes up to?
I looked at filter minders on Ebay and found one for Cummins that goes up to 25" of H20 for $25.. Being cheap I found this one for $15 that goes to 25 too. You do not need the electrical connection that comes with it.
Since I have some small clear plastic tubing I would fill a 6' section half full with water and attach it to the filter minder. With a loop in the tubing and the minder at the top I would lower the open end until it goes into the red. If you have 25" of difference in the water levels the minder is good.

Mine does go to 25".

I talked to a Filter Minder area rep yesterday and he said the Minders rarely loose more that 1-2% of their calibration over 10 years. My problem is far more likely a ducting design or faulty filter issue. My be just covering but that is what he told me.

I like your water tubing test idea. I will pick up some tubing this weekend and measure the gauge. Thanks.

Brett, this may come down to replacing the filter again to make sure this one is not defective or overly restrictive. But if I go to that hassle level, I think I will try and see what optional larger filters I can accommodate as described in an earlier post by Ivylog. I can handle a 13" diameter if I can get the ducting to line up and the strap mounts to fit. Then it come down to answering the key question, "is it all worth it?".
