Whether it will pass muster (i.e. field approval) depends on your FSDO and whether the guy who handles it has PMS or not. I hear fuel gauges are tough. I hear oil pressure and temp gauges are easy. The conundrum with the 'Coupe is that the TSO'd gauges for things like oil pressure that are still in production have a range which is far too high at the high end. The ones that are the correct range are not TSO'd. The TSO'd ones start at 170 degrees. And the TSO'd oil pressure gauges run up to 120 pounds (for a C85 yet!). I was lucky and dodged the bullet when my oil temp gauge went flooey... ...a local A&P had a 20-year-old new-in-the-box TSO'd Stewart Warner gauge. But my pressure gauge looks like crap, and I'd love to replace it. But am avoiding the hassle. In truth, the non-TSO'd electronic gauges with the classic look make so much more sense than capillary tubes running all over the place waiting to leak. Just one more reason why we NEED owner-maintenance to get passed as per our more intelligent northern neighbors.
