What buyers should know first
Fuel scope is often where generator quotations become unclear. A base tank, day tank, bulk tank, transfer pump, and fuel piping are different items, and the purchaser should know which parts belong in the generator supplier scope.
For Yangzhou Tesla Power Equipment Co., Ltd., the useful RFQ usually starts with load size, duty rating, site conditions, voltage and frequency, enclosure style, control requirements, and the documents the purchaser needs for project approval.
In practice
For industrial standby and prime projects, the correct question is not only how many liters the tank holds. Buyers should connect tank capacity to load percentage, expected running hours, refill access, local rules, and whether the generator supplier or site contractor owns fuel transfer design.
| Fuel item | Procurement question | Document to request |
|---|---|---|
| Base tank | Is it integrated with the generator base frame? | Tank drawing and usable capacity |
| Day tank | Is it separate and fitted with level control? | General arrangement and alarm list |
| Transfer pump | Manual, automatic, duty/standby, or site supplied? | Pump control description |
| Runtime | At which load percentage is runtime calculated? | Fuel consumption reference and assumptions |
Specification points to confirm
- State whether the generator is standby, prime, or continuous duty.
- Ask whether quoted tank capacity is total volume or usable fuel volume.
- Confirm if low fuel level, high fuel level, and bund alarm signals are required.
- Define refill access for containerized or soundproof sets.
- Check whether local fire and environmental rules affect tank construction.
Common mistakes to avoid
- Comparing tank size without checking the load percentage used for runtime.
- Assuming fuel piping and bulk storage are included in a generator set quotation.
- Forgetting fuel access around outdoor silent canopies or containerized packages.
- Missing alarm signals that the facility monitoring system expects.
Before requesting a quotation
Ask the supplier to separate the generator set scope from the site installation scope. The generator quotation can normally define the set, enclosure or frame, control panel, breaker, radiator arrangement, silencer, batteries, drawings, and test documents. Civil works, fuel piping, exhaust duct routing, cables, and local approval items should be checked with the site contractor unless they are explicitly included.
- Required running hours at expected load percentage.
- Indoor, outdoor, containerized, or open generator arrangement.
- Fuel tank type requested by the project specification.
- Need for transfer pump, level switch, leakage alarm, or remote monitoring signal.
- Any destination-country compliance documents the importer must review.

Questions purchasers often ask
Is a base tank the same as a day tank?
No. A base tank is usually integrated under the generator set, while a day tank can be a separate fuel tank with its own controls. The project specification should name the required arrangement.
How should runtime be stated in an RFQ?
State the expected running hours and the assumed load percentage. Runtime at 75 percent load is not the same as runtime at full load.
Who designs the fuel transfer line?
That depends on project scope. The generator supplier may provide a package proposal, but site piping, bulk tank location, and local approval items often belong to the installation contractor.
What alarms are useful for fuel systems?
Low fuel level, high fuel level, transfer pump fault, and leakage or bund alarm can be useful when the facility has remote monitoring or strict maintenance routines.
