Question about oil pressure sender?
 

Changing out my oil pressure sender (got the upgraded one Randy suggested) and was wondering if i need to drain the oil before i swap this out?

nope.

Don't forget to put teflon on the threads.

Just swapped it out. Easy like everyone said, but a little oil does spill out. i guess it's the oil from the filter. Thanks.

What was the old one doing?

Oil pressure gauge would stay to left when i started the car and would jump to normal after the car warmed up for about 5 minutes.

Awesome.....I am having the exact same problem. Accept, mine will jump up when I tap the throttle, but after a few minutes stays up. I have a sender on order.

Make sure and order the upgraded sender, part # 6U5Z-9278-D. Randy was the one that told me what my oil gauge problem was and told me about this updated sender, alot of problems with the original one.

screw that get a real guage. the stock one tells you nothing.
