Firman Generator Carburetor Numbers: Are You Using The Right One?
Firman generator carburetor part numbers by model
The most useful carburetor part numbers I found for Firman generator owners are 080522dfws42-H07553 for the H07553 and H07551 dual-fuel 7500/9400-watt units, 380723515 for the H07553/H07552 tri-fuel listing, and 330723572 for the SFE175/171CC engine family; Firman also directs owners to use the model number lookup on its documentation page to match the correct part before ordering.
Fast model guide
If you are trying to identify the right carburetor part, the model code on the generator label is the starting point because Firman's own support pages point users to model-based manuals, parts listings, and wiring diagrams.
| Firman model | Reported carburetor part number | Source note | Fitment confidence |
|---|---|---|---|
| H07553 | 080522dfws42-H07553 | Replacement carburetor listing specifically says it fits H07553 and H07551. | High |
| H07551 | 080522dfws42-H07553 | Same listing names H07551 as a fit model. | High |
| H07553 / H07552 | 380723515 | Marketplace listing describes a tri-fuel replacement carburetor for H07553 and H07552. | Medium |
| SFE175 / 171CC engines | 330723572 | Parts catalog entry identifies a carb assembly for the SFE175/171CC engine family. | Medium |
| P03608 | Not confirmed in the sources reviewed | Parts retailers list P03608-related carburetor and repair-kit options, but the exact OEM cross-reference should be verified by manual. | Low |
What the numbers mean
Firman part numbers are often tied to either the generator model itself or the engine family that powers it, which is why a carburetor listing may mention several compatible models instead of one exact machine.
In practice, that means a search for a replacement carburetor should always be checked against the model plate, because two generators with similar wattage can still use different fuel systems, gaskets, or bowl assemblies.
Model-by-model notes
The clearest match in the sources is the dual-fuel 7500/9400-watt set: one replacement carburetor page explicitly states that part 080522dfws42-H07553 fits H07553 and H07551.
For the H07553 family, another listing identifies carburetor 380723515 and says it is compatible with H07553 and H07552 in a tri-fuel configuration, which suggests that fuel-system variant matters as much as the generator nameplate.
For the P03603 and related P036xx family, the sources reviewed showed the generator model itself and related parts, but not a single clearly verified OEM carburetor cross-reference; that is a sign to confirm via the official model lookup or manual before buying.
For P03608, a parts specialist page confirms the model exists and offers carburetor and repair-kit options, but the exact OEM part number was not visible in the snippets reviewed, so it should be treated as an ordering lead rather than final proof.
How to match the right part
Correct carburetor matching is usually a three-step process: read the model number from the generator label, open the corresponding parts list or manual, and verify whether the part is sold as a carburetor assembly, a repair kit, or a fuel-system package with gaskets.
- Find the exact model code on the unit tag, not just the wattage rating.
- Check the official Firman downloads page for the model-specific manual or parts list.
- Compare the carburetor part number, gasket set, and engine family before ordering.
- Confirm whether your unit is gas, dual-fuel, or tri-fuel, because listings often split by fuel system.
Why fitment mistakes happen
Carburetor mistakes are common because online listings often group similar machines together, and a single product page may cover multiple model codes, such as H07553 and H07551 on one page or H07553 and H07552 on another.
Another issue is that retail parts stores sometimes index by engine family instead of generator model, so a search result may show a carb assembly for SFE175/171CC even when the user is holding a different Firman frame model.
According to the model-based documentation approach on Firman's own site, the safest workflow is to identify the unit first and the carburetor second, not the other way around.
Illustrative reference set
The following quick-reference list summarizes the most actionable part numbers found in the reviewed sources for Firman models and should help narrow a replacement search quickly.
- 080522dfws42-H07553 - listed for H07553 and H07551 dual-fuel generators.
- 380723515 - listed for H07553 and H07552 tri-fuel-compatible units.
- 330723572 - listed as a carb assembly for SFE175/171CC engine applications.
- Unknown/verify in manual - P03603 and P03608 need manual confirmation from the model-specific parts breakdown.
Buying tips
Before ordering, compare photos of the linkage, choke lever, fuel inlet, and gasket shape, because a part number alone does not always guarantee a perfect bolt-on match across fuel variants.
For older or hard-to-read units, search the exact model number plus the phrase parts listing, then match the carburetor diagram to your engine code rather than relying only on wattage or series names.
Retail listings in the reviewed results also show that some sellers bundle the carburetor with gaskets, which is useful because the existing gasket set often fails at the same time as the carb itself.
Historical context
Firman's current documentation page, updated in late 2025, emphasizes downloadable unit manuals, parts listings, and wiring diagrams, reflecting a broader industry shift toward model-specific self-service parts lookup rather than universal carburetor charts.
That shift matters because the modern generator market includes gas, dual-fuel, and tri-fuel variants with overlapping names but different fuel components, which makes model-level verification more reliable than generic search terms.
FAQ
Practical takeaway
The fastest way to buy the right generator carburetor is to match your exact Firman model to a model-specific listing, starting with H07553/H07551 = 080522dfws42-H07553 and checking whether your unit is dual-fuel or tri-fuel before you order.
If your model is in the P036xx family or another less clearly mapped series, use the official downloads page and the parts diagram as the final authority, because the closest retail listing is not always the correct OEM cross-reference.
