Q: I have a 1966 BSA Spitfire Hornet (A65) and I want to install an oil pressure gauge. How is that best accomplished and where do I tap into the engine?
— John Damon/via email
A: From my limited knowledge and research, it's not feasible to fit a pressure gauge on earlier A65 cases. You can fit one using an old oil pressure relief body for testing purposes, but you then give up the pressure relief aspect of the valve, so you really can't use it daily.
