for those who bought the glowshift oil pressure
 

i have 3.4
how easy was the sender unit
and any extra parts i got to buy??

Idk about the 3.4 but I had to buy a thread adapter by autometer to put my oil psi sender in.

I think i needed a thread adapter. Napa had them.

other then that, probably a socket to remove the old one... nothing major.

USE THREAD SEALANT ON THE SENDING UNIT! (teflon tape)

did you have to lower the size of the thread

I think increase. But i don't really remember. Take your OEM unit out, and take it to napa with the new one. (if they are different) they'll set you up.

Use teflon paste instead of tape

i use both on air fittings, both seem to work just as well when used properly. paste is easier to put on though

I used tape with mine worked just fine.
