I purchased an o-ring kit that is specific for my 91 hatch from Autozone and comparing them to the factory black o-rings they are not quite as thick as the factory o-rings. I was wondering if anyone has used these? Part# is MT 2561. I really don't want to have to change them out again if they leak. They do look like they would work, but I want to make sure. Also does anyone know what size the o-ring is on the pressure switch? None of the o-rings in the kit fit it. Thanks for any help.

 

They have a small universal tackle box of universal O-rings I picked up that were 2 to 3 times thicker than the OEM units for my 92. You might need to check out an AutoZone that does commercial sales.

 

Anyone have any other input on this?
