Fuel filler question???

[paintedreams]

I recently changed my truck to a dually with a flat bed and now I just about have to lay on my side to put fuel in it. I thought I would just extend my hose but not sure on what material to use? Please help?? Thanks Dewey

when I changed my bed I bought some diesel rated fuel filler hose from NAPA but be warned the stuff was very expensive...but has lasted 3 years so far.
