When we got 4158, the fuel tank filler neck had a welded 3/8 nipple near the top, with a 3/8 hose drop for an overflow or vent.

However it also had an an 8 fitting on the tank itself, with a 1/2" hose looped around itself and zip tied to the frame. Hose was just pushed on to the fitting and clamped - which seems a little rigged.

Are these both vents? Seems like the AN fitting should connect to the filler vent itself, rather than 2 lines.
