So I bought a JPI fs-450 and I need to get the fittings so we can install it. How can you tell what size fittings the plane has? My mechanic told me it will either be a 6 or a 4. So I went to go look and cant find anything stamped on what I can see just looking in. Is there a standard or will something on the fitting tell me? This is on a Cherokee 180.
