or.. the Oil pressure Sender as rock auto labels them (had a heck of time finding them) also, what should I use (if anything) to seal it? Best as I can tell, this seems to be the main cause of my large oil leak thanks!
PS 57 should be the correct one for a light . I'm sure the PS 57 T is the same but I don't know what the " T " stands for . Both of those are the Standard line of switches which I would stick with
It's an idiot light switch. All of those will work. They turn the light on a 5-7 psi. You should be running a gauge as well.
Thread sealer is best, or tape. https://shop.advanceautoparts.com/p/permatex-high-temperature-thread-sealant-2-oz-59214/7010664-P
Actually it is better to use NO sealer on the threads . Sealer tends to insulate the sender and the way it works is that it has to ground the sender to activate the light . The threads are Pipe Thread and will seal when tightened .
Always learn something new…. Btw these are hard to find right now…Napa had to order from several states away and carquest/advance had no stock of any sort….
