Fuel Metering Pump 24V AL3-D6L & HS3-D5L/D6L

Espar OEM 24V Fuel Metering Pump — Airtronic AL3-D6L & Hydronic HS3-D5L/D6L

Keep fuel delivery precise and reliable with this genuine OEM Espar / Eberspaecher replacement fuel metering pump (FMP). Engineered specifically for 24V systems, this FMP is a direct replacement for both the Airtronic AL3-D6L air heater and the Hydronic HS3-D5L/D6L coolant heater — ensuring factory-spec fuel flow and combustion performance.

A faulty FMP is one of the most common causes of heater lockout and ignition failure. Replacing it with an OEM unit restores consistent, fault-free operation.
