okay well a few months back i bought an oil psi gauge and tried installing it

tried looking for the sending unit thing that u have to take out to tap the gauge into
thought i had found it and ending up being power steering fluid, found this out because i was trying to get it to fit for so long that i had a bucket full of power steering fluid, didnt know i needed the adapter....

so now i bought the adapter from summit...

and im wondering if someone could point me in the rite direction to where the sending unit for the oil is...

its a b13 with a ga16, im sure its pretty sure close to where ur guy's sr20 ones are...

so maybe a part that its close to? or maybe its under a certain intake pipe 123 or 4??

i dont know just trying to find an easier way the guess and check and wasting fluid?

Thanks!!!

i think its on the back side of the motor accesable from underneath

i know that...more direct maybe?
