Feuling Parts - Ventilated Gauge (Manufacturer's Ref: 3085)

Ventilated oil gauge designed to relieve pressure from the crankcase via a PCV-type breather, with oil separator, perforated disc, and replaceable filter. This unit screws into the original oil fill opening, replacing the original part and preventing undesirable blow-by pressure accumulation in the reservoir.

• PCV-type breather with non-return valve and integrated oil separator.
• Replaceable internal filter; perforated disc for consistent ventilation.
• Two ventilation options: 1/8" NPT fitting with internal filter or quick connector with rubber hose and filter.
• Two methods for reading the oil level: bike on side stand (FHS) or upright and level (FHU).
• Installation: screws in place of the original oil fill opening.

According to tests, good ventilation can reduce apparent blow-by and contribute to a stable oil level; Feuling recommends a warm oil level at 90–99%. Caution: the suction opening is located on the right side of the engine, and running the bike on the side stand heats and fills the crankcase, skewing the reading. The gauge becomes hot — use a glove for handling. Made in the USA.

Compatible with Vintage/Classic and Road/Touring universes; cited examples: Harley-Davidson FXLRST, FXLRS, FXBR (models 1923 / 117 H.O.).
