Fuel storage can become a project risk when the diesel generator quotation only lists tank capacity. For factories, hospitals, mining camps, and remote sites, the purchaser should also define containment, filling access, runtime target, inspection space, and who is responsible for site fuel-system compliance.
What buyers should know first
A bunded fuel tank is used to help contain fuel if the primary tank leaks, but the required arrangement depends on the project location and local rules. Yangzhou Tesla Power Equipment Co., Ltd. should receive the expected running hours, load percentage, installation location, refueling method, and any site-specific containment request before preparing the generator package quotation.
Fuel tank scope to confirm
| Item | Why it matters | RFQ detail to provide |
|---|---|---|
| Runtime target | Capacity should be tied to load, not only liters. | Required hours at a stated load percentage. |
| Tank type | Base tank, day tank, and external tank have different interfaces. | Preferred tank arrangement and installation location. |
| Containment | Leak control may be required by the project owner or local rules. | Bunded tank request, inspection access, and alarm needs. |
| Filling method | Remote or enclosed sites need practical refill access. | Fill point, venting, overflow concern, and truck access. |
| Maintenance | Stored fuel can degrade and collect water. | Inspection interval, drain access, and fuel treatment plan. |
In practice
For standby projects, a large tank may look attractive but can create fuel-quality issues if the generator rarely runs and fuel is not managed. For prime or remote projects, the same tank capacity may be too small if refueling is difficult during bad weather or site shutdowns.
Related internal checks include day tank and fuel transfer planning, fuel return line checks for day tank installations, and fuel quality checks for standby projects. For a silent standby package reference, review the 30kW to 60kW soundproof Cummins diesel generator set with ATS option.
Before requesting a quotation
- State whether the generator will be standby, prime, or temporary power.
- Define runtime in hours at a realistic load percentage.
- Confirm whether a base tank, separate day tank, or external bulk tank is expected.
- Ask for tank drawing details, fill point, drain point, and service clearance.
- Request the site engineer to confirm containment and fire-interface requirements.
Questions purchasers often ask
Is tank volume enough to compare quotations?
No. Compare runtime at load, tank arrangement, containment, filling access, and included accessories.
Does every generator need a bunded tank?
Not always. The need depends on local site requirements, installation location, fuel volume, and project owner standards.
Can the day tank be supplied separately?
Yes, but the fuel supply line, return line, level controls, pump scope, and alarm signals should be defined.
What should be checked for standby fuel?
Ask about water drainage, fuel inspection, filtration, and maintenance planning because standby fuel can sit for long periods.
Who approves fuel-system compliance?
The site owner, local authority, or project engineer normally approves local compliance. The supplier can support the package information needed for review.
