can someone tell me the location of the sending unit i cant find it and my oil pressure is always maxed as high as it goes on the gauge as it heats up and were i can get an oem one for replacement   thanks!

I neglected to mention before ... it's for a '87 without intercooler.   I'm looking for a 12a or 14g or 16g in either newly refurbished or very good working condition.   Are the inlet and outlet diameters and the installation procedure identical for the 14g and 16g and stock?   Thanks.   -Chris
