Built for Riders. eAuto Fuel Pump Assembly for Yamaha FZ FI V2 / FZ-S FI V2 / FAZER FI V2 (2014–2018) | 149cc Air-Cooled FI The eAuto fuel pump assembly covers the complete Yamaha FZ FI V2 generation — the second-generation FZ series launched in India in July 2014 with a 149cc fuel-injected air-cooled engine. This includes the FZ FI V2, FZ-S FI V2, and FAZER FI V2 — all three models share the same fuel tank architecture and pump module. The assembly is also compatible with the brief FZ-S V3 BS4 transition variant sold in early-to-mid 2019 before the BS6 switchover. Every unit is tested for correct fuel pressure output and electrical function before dispatch from eAuto.co.in. eAuto Key Specs: 149cc Air-Cooled FI | FZ FI V2 / FZ-S FI V2 / FAZER FI V2 | 2014–2018 | OEM Ref: 2GS-E3907-00 ✅ eAuto Verified Fitment — Fits These Models Model Year Range Engine Yamaha FZ FI V2 (FZ-FI 2.0) 2014–2018 149cc, Air-Cooled, SOHC, 2-Valve, FI, 5-Speed Yamaha FZ-S FI V2 (FZ-S 2.0) 2014–2018 149cc, Air-Cooled, SOHC, 2-Valve, FI, 5-Speed Yamaha FAZER FI V2 2014–2018 149cc, Air-Cooled, SOHC, 2-Valve, FI, 5-Speed Yamaha FZ-S V3 BS4 (early 2019) Jan–Oct 2019 149cc, Air-Cooled, FI, BS4 — retained same tank and pump module as V2 ⚠ Does NOT Fit — Do Not Order For These Models Model Reason Yamaha FZ 16 / FZ-S V1 (2008–2013) Carbureted engine — no fuel pump required Yamaha FZ V3 BS6 / FZ-S V3 BS6 (Nov 2019–Present) BS6 platform uses a different pump (OEM: B9P-E3907-00) — eAuto makes a separate assembly Yamaha FZ-X (2021–Present) FZ-X uses the BS6 FZ V3 pump (B9P) — not compatible with this V2 assembly Yamaha FZ 25 / FAZER 250 (249cc) Completely different 249cc engine — separate fuel pump (OEM: 20P-F4486-00) Yamaha R15 (all versions) Liquid-cooled 155cc platform — entirely different pump architecture Technical Specifications Brand eAuto — Trusted by Mechanics.

The FZ V2's fuel-injected engine is sensitive to pressure drop — even a partially failing pump will affect starting and throttle response well before complete failure. No priming buzz when key is turned on — The pump should pre-pressurise for ~2 seconds on ignition. No buzz means the pump motor has failed. This is the most common and easiest-to-diagnose symptom on the FZ V2. Hard starting, especially cold — An ageing pump builds pressure slowly after overnight parking, requiring multiple cranks before the engine fires on cold mornings. Stalling at low fuel levels — Sediment at the bottom of the tank clogs the pump strainer,
