I am the proud owner of a GTV6 Callaway 1986. The hose that connects the fuel tank with the part where pump’s fuel-nozzle goes when you are filling up the car with gas is broken and so far seems impossible to find a replacement. Anyone can help me here? Any ideas or advices on how to solve this problem? One issue that I noticed is that each end of the hose have different diameters so can’t use a universal hose.
