Transportation Safety Board of Canada Railway Investigation Report R94T0029 [27] section 1.13.1 documents DOT-112 tank car and DOT-114 tank car standards: the DOT-111 tank "cars are not considered to provide the same degree of derailment protection against loss of product as the classification 112 and 114 cars, designed to carry flammable gases."
The average fuel tank capacity for cars is 50–60 L (12–16 US gal). [3] The most common materials for fuel tanks are metal or plastic. Metal (steel or aluminium) fuel tanks are usually built by welding stamped sheetmetal parts together. Plastic fuel tanks usually built using blow molding, which allows more complex shapes to be used.
The placement of the car's fuel tank was the result of both conservative industry practice of the time as well as the uncertain regulatory environment during the development and early sales periods of the car. Ford was accused of knowing the car had an unsafe tank placement and then forgoing design changes based on an internal cost-benefit ...

A tank truck, gas truck, fuel truck, or tanker truck (American English) or tanker (British English) is a motor vehicle designed to carry liquids or gases on roads. The largest such vehicles are similar to railroad tank cars, which are also designed to carry liquid loads. Many variants exist due to the wide variety of liquids that can be ...
Fuel tanks of a capacity greater than 25 US gallons must adhere to specifications for spillage, leakage, mounting, impact survivability, weld requirements, venting and a host of other stipulations. The regulations require side-mounted fuel tanks to survive a 30-foot drop test, while non-side-mounted fuel tanks must survive a 10-foot drop test.
Diagram showing construction of the DOT 117 tank car. The DOT-117 (TC-117 in Canada) is a type of unpressurized tank car in use on North American railroads. The DOT-117 design was developed in the aftermath of the Lac-Mégantic rail disaster of 2013 in an effort to upgrade the specifications of the then-common DOT-111 and CPC-1232 designs. [1]
The repair for this type of problem depends on the severity of the deposits. In milder cases, a mechanic may solve the problem by adding a can of fuel-injector cleaner into the gas tank. However, in some cases, the fuel injectors must be replaced. Deposits formed on the intake valves may be removed via walnut shell blasting.
