Fuel line

[spareparts]

Use marine rated A1 fuel line for below deck, B1 can be used above deck. I avoid anything that has a liner, sooner or later it separates from the inside of the fuel line. take a short piece, cut it lengthwise and see if it has a liner. The grey stuff varies greatly due the manufacture. Some of it will kink real easy, most of it has the internal liner. Its hard to beat the heavy black fuel line.
