1988 convertible oil pressure sender

Hi guys.

I can't seem to find in the service manual how to replace the oil pressure sender?

For that matter... Where it is...

looks like a Bell shaped sender under the oil filter/pedestal area.
has a single wire going to it.

it takes a 17mm I believe,wrench..kind of tricky to get at the base of it ,but doable with a wrench.
If you have a hard time then you may need to take the 2 10mm nuts off the bottom of the oil pedestal and gain more visibility to it.(then you may need to get 2 new Orings that are needed under the pedestal too.)

The pedestal isn't really in the way that much, if anything, it's the water temp sending unit that's an obstruction (but not terrible).

ah,thanks for clearing that up Ben.
I just changed one about 5 days ago,and I found it to be a little funky to get at,BUT I did do it with a small stubby wrench from the back side of the engine.
The Water temp sensor does get in the way but if you work at it carefully,once you get the oil sensor moving you can just grab it at the Bell part and twist it off.

Awesome guys!!

So I'll just time it with my next oil change? Seems to make the most sense.
