Okay for everyone whos searching for a perfect “T” - I just ordered one from TunerToys.com and got it the next day. Fuckin superb cause I live in Hawaii too. Instead of hunting for one online or at plumbing shops you can get one at TunerToys with all PERFECT ends (1/8" BPT male and female, and NPT female with another optional hole) for 20 bucks. These things are BEEFY and are made out of steel (also coated to protect oxidation), AND you can run it off your block without worrying of it breaking off (most T’s are made out of brass and usually break). Highly recommened for people who want to run a stock oil pressure switch and turbo and/or oil gauge.
Heres what I got:
