Anyone know off hand what the thread size is on the 2.8/3.4 block for the oil pressure sending unit? I need to find a copper t adaptor so I can run an oil feed line to my supercharger that is being mounted in the ac compressor location.
1/4 female pipe thread on the factory extension tube for Fieros with A/C.
1/8 female pipe thread on the actual engine block itself.
I have the 88 oil pressure sender in a stock-ish location (for A/C cars), and I killed one when rainwater entered via the decklid vent.
I replaced the sender and packed the connector with dielectric grease, until it was oozing out when I clipped the connector... it's doing OK for now, but I'm not sure it's a very robust solution.
You may want to move the sender elsewhere, where it is more sheltered from water.
