I’ve had issues with a fuel smell coming from the cabin air ever since I’ve installed the OCC. I’ve replaced the gaskets and added thread sealants. Any other ideas before I completely do away with it?
Maybe your hoses are somewhat permeable to the fuel/oil liquid/vapors? Are you sure your hoses are clamped and providing a good seal on all of the fittings? Posted via the PriusChat mobile app.
I got Goodyear fuel line hose that said it was oil resistant rubber reinforced with woven polyester. I checked all the fittings and connections.
Does your OCC have a dipstick? I put a small o-ring under the threaded portion of my dipstick because I didn't think it was vapor tight. I have subsequently removed the dipstick and replaced it with a stainless steel cap screw, again with the o-ring. Posted via the PriusChat mobile app.
