Does anyone know what the thread size/pitch is for the Superior engine dipstick tube? It is a very nicely machined system, and I would like to cobble together some fittings (PVC or otherwise) to enhance oil filling after an oil/filter change. The Phillips supplied free filler tube just doesn't stay put.
I have tried the common True Value plumbing fitting, but they just don't fit. I suspect that it could be metric.
