The MS162 tank caps are a two piece set for MS162 chainsaws, one fuel cap and one oil cap. Black plastic with a wide ribbed grip, a rectangular slot in the center and a T shaped tether handle on the side. The fuel cap has a long stem with a small vent hole that breathes the tank against swelling and leaks; the oil cap has a short stem that seals the bar oil tank. While refilling, the tether hooks over the tank rim so the cap cannot fall in; when a cap is too tight, the pull handle or a flat tool goes into the center slot for leverage. Replace the pair when the stem cracks, the tether bends or the grip ribs break and the cap spins; fuel seeping at the tank mouth points at the cap seal first. This set is made for MS162 tank seats; for the MS172 from the same generation, compare the old cap size and the tank seat, or send a photo to confirm.
