Harley-Davidson X440 / Hero Mavrick 440 Fuel Pump Filter (In-Tank Strainer) – Genuine Hero – HDH16701ACD001S / 16701ACD001S

Fuel-injected 440-platform bikes depend on clean, consistent fuel flow. If your bike starts hesitating at higher RPM, feels slightly “choked” under load, or shows delayed throttle response, a clogged fuel pump filter (in-tank strainer) is one of the most overlooked causes—especially with dusty conditions and varying fuel quality.

HDH16701ACD001S / 16701ACD001S is listed as a Fuel Pump Filter (manufacturer/brand: HERO) and is intended to protect the pump and injector system by trapping contaminants before they circulate through the fuel line. 

This is the “do it right” approach versus running contaminated fuel through the pump (which can shorten pump life and create repeat fuel-system issues). If you’re building a proper maintenance plan for your Harley-Davidson X440 / 440X or Hero Mavrick 440, pairing the correct fuel filter with timely service prevents downtime and expensive fuel-pump replacements.
