After the sheet is cut to the shapes needed, various pieces are bent to create the basic shell and/or ends and baffles for the tank.

Then the craftsmen must determine the thickness, temper and alloy of the sheet he will use to make the tank. Next, design issues that affect the structure of the tank areĪddressed - such as where the outlet, drain, fluid level indicator, seams, and baffles go. The craftsman generally creates a mockup to determine the accurate size and shape of the tank, usually out of foam board.
ETANK SYSTEM BACKUP SERIES
Construction of fuel tanks follows a series of specific steps. These include custom and restoration tanks for automotive, aircraft, motorcycles, boats and even tractors. While most tanks are manufactured, some fuel tanks are still fabricated by metal craftsmen or hand-made in the case of bladder-style tanks.

In the U.S., Underwriters Laboratories approved (UL 142) tanks would be a minimum design consideration.įuel tank for the Apollo Lunar Module, 1960s Emergencies aside, HDPE plastic is suitable for short term storage of diesel and gasoline. The flammability of fuel makes stress cracking a possible cause of catastrophic failure. Plastic ( high-density polyethylene HDPE) as a fuel tank material of construction, while functionally viable in the short term, has a long term potential to become saturated as fuels such as diesel and gasoline permeate the HDPE material.Ĭonsidering the inertia and kinetic energy of fuel in a plastic tank being transported by a vehicle, environmental stress cracking is a definite potential. Anticipate potentials for damage and provide safe survival potential.Feeding of the engine (through a pump).Venting (if over-pressure is not allowed, the fuel vapors must be managed through valves).Provide a method for determining level of fuel in tank, gauging (the remaining quantity of fuel in the tank must be measured or evaluated).Filling: the fuel tank must be filled in a secure way, without sparks.Storage of fuel: the system must contain a given quantity of fuel and must avoid leakage and limit evaporative emissions.Typically, a fuel tank must allow or provide the following:
