You can replace it with a rubber fuel line. If you want to keep the quick connect fittings, just take a box cutter and lightly cut the nylon tubing lengthwise over the barbs on the fitting, and then the line will split off the fitting, and you can keep the fittings. Find some rubber fuel hose, shove the fittings up in there, and away you go.
