SOLER RS provides FIA-FT3-1999 approved fabriqués en bladder-type fuel tanks made of reinforced material enveloped in two layers of elastomer.*

Our products are bespoke, and are manufactured at our workshops in the Tarn region of France.

We use high-tech materials that have powerful chemical properties specially blended to be able to withstand hydrocarbon damage and extreme use.

* A polymer that has ‘elastic’ properties, achieved after treatment. It will withstand a great deal of deformity before breaking. A common synonym for it is rubber.



SOLER RS fuel cell tanks are tailor-made, and manufactured per unit. They are carefully designed to meet your needs.

In order to comply with FIA FT3-1999 standards, our bladder-type fuel tanks are made using high-tech, high-performance materials. This involves having a polyester core that’s enclosed within two layers of industry-treated rubber handled by weaving specialists. That’s the reason the material is also used for water, air and defence vehicles.

The product’s cut-out and assembly are carried out entirely by hand.

Our craftsmanship ensures that the welding is highly resistant to hydrocarbons.

Moreover, we fit our ready-to-mount tanks with a cover and accessories (including hoses, submerged pumps, aviation-type connections, FIA valves and gauges) in conformity with regulation FIA-FT3-1999.

For a comprehensive solution, we also supply the aluminium casing in line with your dimensions.

We are happy to give you support and advice on the design of your tank.
