Light-Weight Fuel Tanks

'Plastic fuel tanks can decrease vehicle weight and incidence of corrosion.' The American Chemistry Council

Lightweight Fuel Tanks

'Plastic tank systems also serve the dual purpose of decreasing the vehicle’s overall weight, as an average plastic tank weighs two-thirds less than an average steel tank.'

'In an Environmental Protection Agency (EPA) comparison test of a steel and plastic fuel system for a 1996 GMT600 passenger van, a steel tank system weighed in at 21.92 kg (48.32 lbs.), while the plastic system weighed only 14.07 kg (31.02 lbs.). (The fuel system tested consisted of three components: a fuel tank, straps to secure tank to frame, and a shield with unique function for each fuel tank system.)'

'In the same EPA test, the lighter weight of the plastic fuel tank system resulted “in significant savings in use phase energy relative to the steel.” This contributes to an overall lower life cycle energy requirement for the plastic tank system, and a potential significant savings in fuel cost.'

'A blow molded fuel tank saved the Audi A6 up to 20% in weight, with an efficient utilization of space, but without risk of corrosion.'

summary: 

Plastic tank systems also serve the dual purpose of decreasing the vehicle’s overall weight, as an average plastic tank weighs two-thirds less than an average steel tank.
