Kinda poking around the Auto Zone site I don't see where these tools are available for rent. Have to stop in and talk to somebody there. I know the store manager of my local Auto Zone. We don't rent them at Napa. At least at mine. They are not in the binder that shows all the tools we do rent.

Borrow what you need for a compression test.

Check your oil pressure with a mechanical gauge. I picked up a Bosch for under $20 (I think it was $16.99 on sale) just for that. Sure it doesn't have a fancy blow-molded case, but it reliably measures oil pressure, and it takes less than 10 minutes to remove the existing sender, connect the Bosch, set it on the cowling where I can watch it, fire it up and read the pressure, then put it all back to stock.

Guessing you bought an actual mechanical gauge like this?
