I don't think NAPA has the POLY tube, it is a hardware store item as it is
used in pressure water lines for desert coolers and such. Fuel line is not
good since it is black and rubbery it requires clamps and the plastic does
not. The barbs are unusually sharp and the hot brass cuts the rubber in
summer causing vacuum leaks.

You are ok if the engine was running when you did the work then you restart
it immediately. If it was already dry you need to somehow pour fuel down the
tube which is a bitch with that knobular end attached. My fave technique is
buy a gallon of "diesel helper", insert the knob in it and the pump easily
pulls up that little ways to prime the pump. This is the same as when the
engine sat for years and the pump is totally dry. You cannot just pull the
knob off the hose for diagnostic work. The real professional has a spare for
that.
