OPSU relocate
I've read about drilling/tapping the bolt-on boss part above the oil filter, but the OPSU threads are almost as big as the OD of the part that it would thread into.

Is there another sender that has smaller threads that would work? My car is a '99 btw, these threads look to be 16mm.

6AN is 9/16-18 which I think would work. I just hope it doesn't make the whole thing too tall to fit under the head (heads and headers are off the car at the moment).

I decided I didn't want the thing so close to the exhaust, so I mounted it off a little bracket I made that bolts to where my new throttle cable comes through the firewall.

A new copper washer for the block fitting, and an O-ring inside the one the sensor screws into. And an 11" hunk of hose with 90 degree ends I got off ebay for like 11 bucks.
