I am going to replace my faulty oil pressure gauge sending unit and two bad exhaust gaskets on Sunday. I have removed the original one before, only to find out the one Kragen's special ordered for me was incorrect, so I put my old one back in until I was ready to get a new one.

So, I have one now, from the dealer where I work, but there is no washer pictured with it and there is no washer on my old unit still in the rotor housing. My question is, do I have to apply some type of thread sealer (like that white tape stuff) for good measure? I just want to make sure it does not leak or anything. Thanks.

I'm also replacing a couple of exhaust gaskets this coming weekend as well, so I'll have my exhaust leak fixed! One line to be deleted off my sig.....

 

use teflon tape
working for me

 

Thanks Greg, again just wanted to make sure 'cause the OEM does not have anything at all.
