Where can the modern vintage aircraft "fuel-proof" yellow hose be found Gordon?Dave, as usual, is very correct. Not only are the banjo fittings different, but the line length is different. On The DCOE series, the banjo fittings are made for a slightly larger diameter brass banjo bolt that the later, non screw end fittings. In short, there are a number of variations potential buyers need to match to their specific application. As I restore these fuel lines, with modern vintage aircraft "fuel-proof" yellow hose, I get to see the variations.
