The stock pressure sender unit does look to be a BSPT. I know this because when I tried to install a BSP (non-tapered) fitting into that spot on the block today (to hook up to a braided line and a remote T), I was unable to do so. Granted, my wrenching skills are modest at best (it took me a few tries to get the stock sensor back in after I gave up on the new fitting), but I think only a BSPT will work. The taper on the stock unit is actually pretty obvious on visual inspection.
I did get the Mishimoto in. Thanks Exigegus for the idea and the fittings! Once I get my temp sensor hooked up (at the pan), I'll try to make some data to share.
Note: The MWR upgrade union bolt is just a tad too thick to fit in the Mishimoto, so I put the stock one back in. I may at some point try to turn a bit off the MWR fitting on my lathe to get it to fit. Does anything think that would be a mistake? I.e., would it mess up the temper or something like that? It is very close so I won't need to shave off much.
Exigegus, the dual sender sounds intriguing. Do you remember where you sourced that?
Or maybe I should just leave the stock OP alone and attach my new OP gauge sensor directly to the Mishimoto? Only one of the ports is accessible, but I only need one. That will vibrate too, but it cannot be any worse I imagine than what the stock OP sensor is doing and that hasn't fallen out yet (although now that I have uninstalled and reinstalled it, maybe it will!). So one sensor vibrating is ok? I am after all putting the temp sensor unit right on the oil pan plug. Are we just trying to avoid attaching to the block some massive contraption with a T and multiple sensors?
Many thanks. And Happy July 4th!
