UL142 Fuel Tank

Double-Wall Design Generator Fuel Tanks

Fidelity Manufacturing delivers standard and custom UL142 sealed secondary containment sub-base tanks for all equipment manufacturers. Tanks are fabricated in a high-quality, controlled environment and are designed to provide you with the best possible solution for your equipment and power generation needs. For your convenience, we structurally offer both side-rail and direct-tank lid mounting options.

Trusted Source for Secondary Containment Tanks

This exceptional style provides a completely sealed secondary tank with pressure control via a secondary venting system. The secondary containment is optimized to capture any liquid escaping from the primary tank due to a breach of integrity. Both the inner and outer tanks are pressure tested prior to installation. Tanks can be shipped under pressure or vacuum if required.  We look forward to providing knowledgeable advice on the right solution for you.

Contact our experts to learn how we exceed the competition in providing products and fuel tank accessory packages that meet UL safety requirements and industry regulations.

High-Quality Fuel Storage Solutions

We provide fuel tanks built according to UL standards and global safety specifications using only UL sized and rated emergency vents and containment systems. Standard design provides a slight slope to one end for water drainage, while keeping the side rails flat for engine and enclosure mounting. The direct lid mounting (structural) option doesn’t incorporate the sloped lid.
