If you dont mind and can part with your current one. Would you be willing to let us have it? Would look into having a jig made and then made in a fuel safe silicone which will last much longer

Don’t know if you have the old one or not . They have hoses including filler neck hoses hanging at some local parts stores. As the parts guy to walk back there with you and your sample pick something that’s close in shape. Maybe much longer but has the right shape and size. Cut to fit. I did this with my mighty max . It’s easy to identify fuel ones they look different
