Vacuum Gauge?

[GuglioLS]

There is a vacume, which increases with an increase in filter restriction. It however is very low and is better measured in inches of water column and not inches of mercury. That gauge pictured(IN/HG) will most likley not move very far off the peg, and then only when you rev the engine, and then only due to lag as the airflow must be accelerated to meet the need. 1" of HG column is equal to roughly 14" H2O column making the water column gauge far more sensitive.

Go with the FilterMinder that SnowRidge recommends. Air cleaner restriction is measured in inches of water, not inches of mercury that an automotive vacuum gauge reads. A filter is usually restricted at 25" of water, if you multiply 25 by .07355 you get 1.8" of mercury. You'll be huffing coal out your stack before you see anything registering on a mercury gauge.

WOW great input gentlemen thanks for the enlightenment! It's settled then, I'm going to send my gauge to Rob

Seriously, I will check into the filter minder, it seems like a cool device, I want one that I can mount on the dash, I think they carry one. Automobile Parts, Air Filter, Fuel Monitor, Car Accessories, Engineered Products

Since there are no prices on the web site or any information on where or how to actualy buy one, I assume it costs an arm and a leg.

Does anyone know where to buy one? Online would be good.

Thanks,
Larry

Larry,

If you have a junk yard around, the newer cars all have the little filter minder deal on them. Probably can get one for a buck.

If you still want a "gauge" I've seen vacuum gauges that read in inches of water, some in really low ranges like 0 to 2 inches. I've seen them in the range of 0 to 25 inches of water vacuum too. I did a quick search but couldn't find one, but I know they're out there.

One thing about the Filter Minders is that I don't think the reading will go up and down dynamically like the first gauge you bought. If that matters.

Something similar to that is on newer(90's on) JD air units...since you check your tractor before you operate it...you don't need it on your dash...if it was close before you start for the day...you replace your filter and you are good to go...Unless you are operating in a sandstorm...

My 2001 JD4100 has one installed on the air cleaner housing.

And if there are any tractor trailer wrecker yards around, they use them also.
I have a Jacobson mower (parts machine) that has one on it, that I thought about putting on my JD.

My 96 Ford Powerstroke has one on the OEM air filter housing...don't know what a Ford dealer gets for one...

All the Dodge Ram Cummins have them as well. Try a junk yard. My NH 2120 has an electric one as OEM. Turns a dash light on when it's time to blow the dust off. NH P/n is SBA385201340
