what does ur oil pressure gauge read when ur car is off? does it stay where it was, move randomly, or return to zero? how about when it isn't even installed in the car. should it matter where the needle sits? thanks

zero

 

Yep zero...drops like a rock.

 

so if i got a secondhand gauge that isnt even connected yet, and its reading at 20, its prob broken huh? damn

 

It's probably the sender that's bad, not the gauge

 

sender? its mechanical. should there be a sender? i thougth only the electric ones have a sender. damn, what a waste of money. i gotta see if i can get my cash back from this guy

 

Yay! i called the guy and asked if he ever used it, and he said he didnt, just pulled it offa the last car he bought. i should be able to get a refund today.

and now i can get an oil pressure gauge that actually matches the boost gauge i bought

there are still good people in this world
