Need help fast! Oil pressure gauge install trouble

[mdost03]

Sounds good DSM_421, car won't be going until about mon-tues hopefully, so no rush.

Well I ended up just taking a 1/8" NPT tap to the hole and threaded the oil pressure sender directly in there with no adaptors. Hopefully it won't leak, but I think it should be ok. Will find out next mon-tues if it needs to be tightened up more or not.
