Wierd gauge question

[g2shuck]

I am needing to take some backprrssure readings in my truck to compare to boost pressure. My question is can I use an ELECTRICAL oil pressure gauge temporarily as a back pressure gauge? The only thing I am not sure of is ill be essentially using it as a air pressure gauge but the oil pressure sending unit it a fluid pressure sending unit

What weighs more, a pound of feathers or a pound of sand. I think you have a good idea there.

At first I was confused by what you were saying but now I get it (I know I know, I'm kinda slow so please forgive me). I think this pretty much answers it.

It should work. Pressure should be measurable as liquid or air in that sending unit.

Don't weigh sand, pound sand!

I gotta ask, how does a pound of anything weigh more than a pound of anything else??

Exactly! So how is 20lbs of back pressure different than 20psi of oil pressure to an electric sending unit?

It's all good man. I'm the butt of many a joke at work ALL the time so don't feel bad. And pressure is pressure. It doesn't matter what fluid is producing the pressure. I know in the plant we measure both liquid and steam pressure with the same instruments.
