Dorman M39777 Brake Master Cylinder Review

This is not a negative review for Revain, this is for Dorman. I am using this as an upgrade for my 240sx autocross machine. This product works well but the tank cap accidentally loosens and won't retighten. Upon closer inspection, the threads on the lid aren't fully severed, so it obviously won't tighten as it should. Unfortunately Dorman says they don't sell parts for this, although it's probably a 0.25 cent limit on them, they force me to remove the entire unit and send it back to Amazon…
