Factory oil pressure sending unit replacement - variable
 

I have been part searching for an alternative to the 94' and under oil pressure sending unit. For anyone with a bad sending unit or swapping to a real pressure gauge it's getting hard to find one and if you do it's very expensive. The closest I have found is from a 260ZX / 280ZX with analog gauge.

Part #
Standard PS153 or search UPC# 0091769020736
BECK/ARNLEY 2010239

It is the correct 1/8" BPT thread
Ohm wise it's very close

Pressure to sending unit - Gauge reads
35psi - 30psi
58psi - 60psi

It has a pin connector instead of a blade terminal so I just solder a crimp blade onto it.

Sending unit on the left is OEM mazda 94 and under and the one on the right is the PS153
