I am replacing the plastic OMP lines with stainless steel lines. The lines I purchased didn't come with o-rings. I have been to the local Advance, Pep Boys, and Autozone, and none of them have O-rings small enough to use.

Does anyone know the size of the OMP oil injector o-rings?

 

You do not use o-rings, it is copper washers. They can be purchased at any Mazda dealer for about $2.50 ea. Call Ray at Malloy Mazda.

 

Yep, I knew they were brass crush washers. Thanks for correcting my terminology. I found a pack of assorted brass washers at an autozone years ago that had small diameter washers, but I haven't since been able to locate one.

$2.50 a piece seems a bit ridiculous, and I was hoping to just go buy a pack of them locally, but oh well...

 

If you have a Harbor Freight, they have an assortment for $10 or you can take an oil injector and one of the OMP line bolts down to your local ACE hardware, they also have copper washers.

 

The copper washers on this car are metric standard sizes, so I've found some of the sizes on mcmaster.com or mdmetric.com

Much cheaper than the OEM price.
