Pretty sure it's a preformed fuel line. Mine sure was(Only God who know's if it was original). I replaced it with 3/8" bulk rubber fuel line (Your's was 1/4" Ralbelt?). Worked fine. Have heard of people having trouble with bulk fuel line collapsing under the pump's vacuum. Just use enough that the bend is nice & gradual - Mine worked fine. (If your fuel pickup is somewhat clogged, you may have collapsing issues.. However, if your pickup is clogged, that's a problem in itself.) Good Luck!
