anyone know the size for the damn oil pressure sender?

i have tryed 22mm, 28 and 34mm none work (well the 28 and 34 are intertwined but the 34 doesnt reach the bolt)

i really want my oil pressure gauge to work, i finally hooked up the water temp.

22mm, but you will need a deep socket to get to the bolt.

btw, when it comes to removing the stock sender, socket extensions are your friend.

22mm is the figure i found on a website when trying to get the idiot sender off my NA8.

i actually used an imperial 6 point socket. it was either 13/16" or 15/16".

measure it with a vernier or calipers if you can get to it.
