Project C4, 85 Corvette

[Steve85]

I wanted the stock dash to work which meant getting the sending units to mount on this engine somewhere. This is the oil temperature gauge location that I used. This is the way Corvette Central did it.


I took that off, assembled some tools and went to work.


Drilled out the 10mm threads and tapped with 1/4" NPT


Somewhere along the line I picked a set of "star" sockets and they work great for square ends


Using a 1/4" nipple, a 1/4" tee and 1/4 to 1/8 reducer bushing I was able to mount the original oil pressure and oil temperature senders. It is installed and wired...
(this was the test fit pic, guess I never took a final pic)


Update - A friend pointed out that the sending unit and fittings will subject to a lot of vibration here and I have to agree. I do have a fitting in the top rear of the block that replaces the original LS oil pressure sender that accepts the old sensor. If I have room to use it (cowl and firewall clearance) I will relocate the sender and just have the temp sender by the filter with no brass tee, screwed directly into the LS fitting.

This is the fitting, ATM-2268:
