it's on the intake side of the motor, low on the block...just looks like a small cylinder, about 1" in diameter, on a small fitting, screwed right into the side of the block. Yes, it's 1/8 BSPT

Look just below the oil filter from under the car.

ok, oil pressure one is taken care of. Now does anyone have any idea about my speedo? I **** a brick whenever I see a cop cause I have no clue what speed I'm going. Can someone at least tell me what rpm's=what speed?I checked all my wiring and I don't know what the problem is on the speedo wiring...

yeah but mine is a daily driver and at the moment the DMV won't let me title the car in my name (because the guy that sold it to me never got it titled in his name, he just gave me a signed title... but HE signed it and since it wasn't titled to him he can't sign the title, so the dmv wants me to find him again (fat chance) and have him title it in his name (and pay taxes on a car he already sold) and title it to me. So basically I don't have registration, and without that I can't get it inspected. ****ty. so I'd like to have a speedo so I can go the speed limit when there are cops around so I don't get pulled over and written like $500 dollars in tickets and possibly getting my car impounded or having my license revoked...
