FAQ
TL;DR: 2003 Yaris 1.0 (French-built) has 0 separate fuel filters; “there is no fuel filter here”—filter is integral to the pump module; Japanese replacements won’t fit. [Elektroda, Eidems, post #16995084]
Why it matters: This FAQ helps DIYers and pros avoid buying the wrong in‑tank filter and shows what to replace instead for this VIN-specific Yaris.
Quick Facts
- French-built 2003 Yaris 1.0 uses a pump-module-only design; no standalone inline filter. [Elektroda, Eidems, post #16995084]
- OEM catalog shows replacement as a complete fuel pump set, not a loose filter. [Elektroda, bandi21, post #16995077]
- Aftermarket codes JPN30F2047JPN, ADT32373, ADT32360 were reported not to fit this VIN. [Elektroda, Eidems, post #16994702]
- The “filter” seen in-tank is a pump strainer; injectors carry their own micro-filters. [Elektroda, andrzej20001, post #16994925]
- Catalogs often list a single filter option for this car, leading to mismatches. [Elektroda, mtd, post #16994649]
Does a 2003 Toyota Yaris 1.0 (post-facelift) have a replaceable fuel filter?
For French-built cars, no. There is “no fuel filter here”; the filter function is inside the fuel pump module in the tank. If you buy a loose in‑tank filter meant for Japanese versions, it will not fit this configuration. Replace the complete module instead. [Elektroda, Eidems, post #16995084]
Why doesn’t JPN30F2047JPN fit my Yaris 1.0 16v 2003?
Because it matches the Japanese-built setup. Your French-built Yaris uses a different in‑tank assembly with no separate service filter, so the Japanese replacement won’t align or seal correctly. The owner confirmed the mismatch and the French build. [Elektroda, Eidems, post #16995084]
What part should I buy to fix fuel filtration on this VIN (VNKJV13380A1999916)?
Order a complete fuel pump module as per the OEM catalog. It consolidates the pump, strainer, and housing. Loose filters aren’t listed as service parts for this configuration. This avoids repeat tank work and fitment issues. [Elektroda, bandi21, post #16995077]
Are ADT32373 or ADT32360 correct for this car?
They were checked and found similar but not correct for the VIN noted. Visual similarity misleads here. If your car shares this configuration, skip these codes and verify against the OEM pump-module listing. [Elektroda, Eidems, post #16994702]
What is the in‑tank ‘pump filter’ or strainer?
It’s a coarse mesh on the pump inlet that screens debris before the pump. It is not the fine filter protecting injectors. As one expert put it, “Pump filter… Disposable filters are in the nozzles themselves.” [Elektroda, andrzej20001, post #16994925]
Do Yaris 1.0 injectors have their own filters?
Yes. Each injector has a micro-filter, making the fuel system largely maintenance‑free. If contamination occurs, the remedy can involve injector service and pump‑module replacement, not a standalone fuel filter swap. [Elektroda, andrzej20001, post #16994925]
Is there a scheduled service interval for the fuel filter on this model?
No separate interval exists because there’s no standalone filter to replace. The system is a maintenance‑free, disposable design; service typically means replacing the entire pump module when needed. [Elektroda, andrzej20001, post #16994925]
Catalogs show only one filter—should I trust it?
Be cautious. One poster noted “this is the only one in catalogs,” yet it didn’t fit the French-built car. Always cross‑check build origin and VIN before ordering to avoid returns. (Statistic: 1 catalog listing mentioned.) [Elektroda, mtd, post #16994649]
How can I tell if my case matches the French-built setup discussed?
If your 2003 1.0 Yaris is French-built and aftermarket in‑tank filters don’t fit, you match this case. The thread’s owner confirmed French manufacture and resolved the issue by recognizing there was no separate filter. [Elektroda, Eidems, post #16995084]
What’s the recommended fix if fuel delivery issues arise on this setup?
Replace the complete fuel pump module. The strainer is part of that assembly, and loose replacements often mismatch. This approach restores flow and filtration in one job. [Elektroda, bandi21, post #16995077]
Edge case: can a look‑alike filter fit but cause problems later?
Yes. A near‑fit can fail to seal, causing pressure loss or leaks after installation. Users reported similar‑looking parts that “are rather not correct” for this VIN. Avoid by sourcing the full OEM‑spec pump module. [Elektroda, Eidems, post #16994702]
Quick how‑to: replace the pump module on this Yaris
- Depressurize fuel system and disconnect battery.
- Access under‑seat tank cover, unplug lines, and remove the pump module.
- Install the new complete module with a fresh seal, reconnect lines, and test. [Elektroda, andrzej20001, post #16994925]
Why do Japanese‑market replacements keep appearing for my EU Yaris?
Aggregated catalogs often merge variants. The thread shows replacements matched the Japanese version, not the French build. This leads to persistent miscataloging and wrong‑part deliveries. Verify by VIN against the OEM pump-module entry. [Elektroda, Eidems, post #16995084]
What was the final resolution from the original poster?
They concluded the car was French‑built, accepted there is no separate filter, and thanked contributors after solving the riddle. The fix path is to avoid standalone filters and use the correct pump module. [Elektroda, Eidems, post #17941245]
If I already bought JPN30F2047JPN, what should I do?
Return or resell it and source the correct complete pump module. The owner said the JPN replacement “does not match,” which aligns with the French‑built configuration. Don’t force‑fit or modify. [Elektroda, Eidems, post #16994398]
Is there any benefit to replacing just the strainer?
On this configuration, no. The strainer is part of a maintenance‑free assembly. “Full fuel pump is installed,” meaning replacement addresses filtration and pumping together for reliable operation. [Elektroda, andrzej20001, post #16994925]
