what size wrench or socket do i use for the oil pressure sending unit? do i just use teflon tape to seal the threads? i noticed that honda uses some green thread sealer liquid... what is that and should i use that instead of teflon tape?

 

15/16" deep-socket

 

its pretty much an OEM liquid teflon. I taped mine and if you don't have a 15/16" deep socket you can use an adjustable end wrench

 

size 24 socket for my accord one..deeeep socket btw
