§182.435. Integral fuel tanks.
46 C.F.R. § 182.435
Gasoline fuel tanks must be independent of the hull.
Diesel fuel tanks may not be built integral with the hull of a vessel unless the hull is made of:
Steel;
Aluminum; or
Fiber reinforced plastic when—
Sandwich construction is not used; or
Sandwich construction is used with only a core material of closed cell polyvinyl chloride or equivalent.
During the initial inspection for certification of a vessel, integral fuel tanks must withstand a hydrostatic pressure test of 35 kPa (5 psig), or the maximum pressure head to which they may be subjected in service, whichever is greater. A standpipe of 3.5 meters (11.5 feet) in height attached to the tank may be filled with water to accomplish the 35 kPa (5 psig) test.
