⚠️ When to Replace
The FZ V3 BS6 platform is now 5+ years old — early adopters from 2019–2020 are entering the replacement window. The BS6 FI system is sensitive to fuel pressure variation. Watch for these signs:
-
No priming buzz on ignition — Turn the key and listen for ~2 seconds of pump pre-pressurisation. No buzz means pump motor failure — the most common and clearest sign.
-
Hard cold starts — 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 strainer, causing the engine to stall at idle when the tank is below one-quarter full.
-
Throttle hesitation / stumble — Inconsistent fuel pressure from a failing pump causes a brief stutter when opening the throttle from standstill or low speed.
-
Flat mid-range performance — Insufficient pressure at higher RPM kills the strong mid-range character the FZ V3 BS6 is known for.
-
FI warning light on cluster — A low fuel pressure ECU fault code illuminates the FI warning indicator on the instrument cluster.
eAuto Tip: FZ-X owners — the FZ-X shares the identical B9P-E3907-00 pump as the FZ V3 BS6. If your FZ-X is stalling in traffic or struggling to start on cold mornings, the fuel pump is a likely culprit. This eAuto assembly is a direct fit.
🔩 Installation Notes
Tank Access: The fuel pump is located inside the fuel tank on the FZ V3 BS6. Full tank removal is required. Depressurise the fuel system by running the engine until it stalls before disconnecting any fuel lines.
BS6 vs BS4 V3: Do NOT use this assembly for the FZ-S V3 BS4 (early 2019). The BS4 V3 uses a different pump (OEM: B4G-E3907-00). eAuto lists a separate assembly for the BS4 variant.
FZ-X: The FZ-X (launched June 2021) is based on the FZ V3 BS6 platform and shares the identical B9P-E3907-00 pump. This eAuto assembly is a direct fit for the FZ-X.
FZ-S V4: The FZ-S V4 BS6 (launched 2023) continues on the same platform and uses the same B9P pump. This assembly covers the V4 as well.
After Fitment: Turn the ignition on (without starting) and listen for the ~2-second priming buzz from inside the tank. This confirms the pump is energised and pressurising correctly before you start the engine.
✔ eAuto Fitment Guarantee: This assembly is verified for Yamaha FZ V3 BS6, FZ-S V3 BS6 (Nov 2019–Present), FZ-X (Jun 2021–Present), and FZ-S V4 BS6 (2023–Present). Contact eAuto support at eAuto.co.in if you are unsure about your exact variant or year.
❓ FAQ
Q: Does this fit the FZ V3 bought in 2020 or 2021?

Q: Does this fit the FZ-X?
A: Yes. The Yamaha FZ-X (launched June 2021) is built on the FZ V3 BS6 platform and uses the identical fuel pump (OEM: B9P-E3907-00). This eAuto assembly is a direct fit.
Q: Does this fit the FZ-S V4 (2023 onwards)?
A: Yes. The FZ-S V4 BS6 continues on the same platform with the same B9P-E3907-00 pump. This assembly covers V4 models.
Q: My FZ V3 is from early 2019 — is it BS4 or BS6?
A: If purchased before November 2019, it is a BS4 model (FZ-S V3 BS4) and uses a different pump (OEM: B4G-E3907-00). eAuto lists a separate assembly for the BS4 variant. If purchased after November 2019, it is BS6 and this assembly applies.
Q: Will this fit my FZ FI V2 (before 2019)?
