5/8" TYPE A1 FUEL FEED HOSE (PER FEET)

Type A1-15 Fuel Line is specially formulated and constructed to meet the strict requirements set out by SAE J1527 Type A1-15 Marine hose and is required for fuel feed lines where the fuel is constantly sitting in the hose in an enclosed engine compartment. This also meets European specifications for small craft fire resistant fuel hose under reference ISO 7840/1994 Marine Fuel.
Specifications for fuel hoses used aboard small craft have been standardized by the Marine Technical Committee of the SAE (Society of Automotive Engineers) under their specification J1527. Hoses can be broken down into four broad groups (A1, A2, B1 & B2) according to fuel permeability and flame resistance.

Fuel Permeability:
Class 1 hoses have the greatest resistance to fuel vapours permeating through the hose itself. Therefore, in enclosed engine compartments where fuel is constantly in the hose, Class 1 hoses should always be used. Class 2 hoses exhibit less resistance to permeation, and so are intended for filler or vent hoses where fuel does not usually lie in the hose, or where there is no threat of fumes collecting in an enclosed area.

Flame Resistance:
Type A hoses have a flame resistant cover and will resist burning. Type B hoses have not been subjected to any flammability tests. Typically, fuel feed lines will be type A1, combining maximum resistance to permeation and to fire. Vent and filler neck hoses will be A2 or B2.
