Oil pressure sender/cutoff switch

[Chryco Psycho]

the big one is the only one I know of that works for the older guages

I'm running a similar set-up, albeit with a slightly smaller sending unit for an aftermarket oil pressure gauge.  I looked for the double 45* fitting that you have, but in the end, just used a T-fitting.  Straight-up to the oil pressure sending unit with the fuel pressure cut-off sticking out of the side.

Can you post a quick pic? Also, where did you get the T fitting? Did you also use a short threaded pipe to get a little extra clearance?

After further review, I was right and wrong.  Because of the distributor, I had to come off the block at a 45, and then go into the Tee.

Sorry for the iffy pic.

To answer the rest of your questions...

Hardware store brass NPT pieces.  (2) close nipples, (1) 45 elbow, (1) tee < $10.

Awesome. Your picture and notes make it clear. Thanks!
