Home Depot, and plumbing stores have braided hose that is 1/4", and 3/8". The ones for a washing machine are 5/8", and the ones for a hot water tank are 3/4". 1/4" is used on ice maker lines for refrigerators, and 3/8" is for faucets, and toilets. You would have to slice the ends off, and use the braided hose in the appropriate size. If you ever want to replace the whole line in the future, you would have to use a fuel line disconnect tool, and connect one of these hoses onto it. You wouldn't need the brass fitting kit for that. The hose would go from end to end without any adapters, just hose clamps on each end.
