Hassle free

quick and easy and had exactly what i was looking for

I would have liked better clarification on part ordered and shipping time. Also on the replacement part, filler neck, the vent tube had a slightly larger flare at the end which was nearly impossible to fit in the OEM fuel vent hose.
