I wouldn't, and in fact, I don' t think you even can re-use the fittings. The fittings will probably be hard to find as well, as I would imagine that they were made special for Honda. Your best bet is going to be finding a longer stock hose. I think someone said the GSR is longer. Other than that, your only other option would be to re-locate the fuel filter so it's closer to the rail.

Good luck.
