Vacuum Fuel Pump Fix Leak & Fuel Starvation For Honda DIO50 AF27 AF28 Lead50 SK50

This vacuum‑operated fuel pump is engineered for Honda two‑stroke scooters. It fits DIO50, Lead50, SK50, AF27, AF28, and also compatible with AF18, AF34, AF35, Lead90, cross‑referenced to OEM part number 16700‑GW0‑023. Driven purely by engine intake vacuum, it requires no extra power supply. Die‑cast zinc alloy housing resists vibration during riding. The inner oil‑resistant rubber diaphragm stands against gasoline corrosion to deliver consistent fuel suction over long service hours. Stock fuel pumps suffer diaphragm degradation after long‑term operation. Common troubles include insufficient fuel flow, jerky acceleration, gasoline leakage and complete pump failure, which leads to hard starting. This aftermarket replacement reproduces original mounting holes and hose ports precisely. No hose modification is required for direct‑fit installation. It works well for professional workshop repair and private scooter maintenance. It effectively resolves fuel‑system malfunctions and restores normal fuel delivery and riding performance for 2‑stroke Honda scooters.
