I struggled with the Motive 1118 cap to keep a good seal on my Model 3. Motive event sent me a few other gaskets. I finally got a decent seal by building up the gasket with some tape. While texting with our Mobile Ranger he sent me a link to the ones they use, produced by JTC Auto Tools:
It beats the heck out of the Motive Cap. Really well built and solid.
To use it, first unscrew/loosen the black part as shown in the first image. Insert the tool in the reservoir's throat. It goes in loosely and easily. Twist the cap so it fits in the locking portions of the reservoir.
Tighten down the black screw. It compresses the rubber ring and seals into the reservoir opening. It held pressure with no leaking whatsoever. I liked I didn't have to force the cap down and under the plastic tabs like the Motive cap, which can chew up the plastic.
Not having to struggle with the seal made using the Motive Power Bleeder dry so much easier.
