Overview
A hands-on owner walk-through of springtime maintenance on a Branson 4720i, covering an oil change (17mm drain plug, Rotella T6, Napa Gold filter #1334), a cartridge-style fuel filter swap (filter #3263, with a live fumble when the spring gets forgotten), and a quick air filter cleaning and radiator check. Specific part numbers and real procedural detail make it genuinely useful for owners doing the same service themselves.
