The oil pressure sensor is a 1/8 bspt thread size. It's very hard to find anything with that thread size because it's like the metric size of fittings. You probably got a 1/8 fitting which will work. Just screw it in once and never take it out. lol.

 

personally i roll to mcmaster-carr for all that ----.

 

That would explain your oil line order tough guy. haha. I caught you!!!

 

uh dude, my first setup used mcmaster fittings... i upgraded to your kit cause its gangsta...

 

you can get a female bsp T and a bsp male nipple from Mcmaster. That screws into the engine, the Oil Pressure Sender screws into the top. Now all you need is a BSP to AN convertor available from Pegasus. That's the cheapest way besides the Tuner Toys thing (which i highly recommend, even though i dont' have it haha).
