HELP i installed an autometer oil pressure gauge eletric, i dunt get it im getting no oil pressure , my gauge stays below 0 , im pretty sure i wired everything up , i see the oil flowing through the nylon hose , so i know that i have oil pressure , i dunno wtf is going on , i also extended the wire on my stock sensor and now when i turn my ignition to the on position my oil light on the dash does not even come on.

 

Where is the sending unit mounted?

List in detailed steps exactly what you did.

 

the unit is mounted in the front of the car , i ran a nylon hose from the block to a T fitting with the stock sensor and sender on it

 

2 more:

A) So your T fitting/sending unit is just hanging off the back of your block (with your sending unit off one of the branches?) Is it braced in any way? If not, this is a potential timebomb.

B) Have you checked your electricals for proper voltage?
