There are 3 basic types of Gates Barricade hose for fuel. Low pressure, high pressure fuel injection, and high pressure submersible for in tank pump to hard line connection.
If you have simple carburated with mechanical or external electric booster pump, you want the first type. If not Barricade type it is obsolete for use with today's fuel. These new hoses have a thermoplastic layer or "barricade". Auto parts stores are not supposed to be selling old type fuel line but there are plenty of old spools of it they need to sell to recoup on. Old type can fail in a very short time. The first time Cinnabar dropped my tanks they did not use the Barricade hose and the line to my Onan started weeping after about 5 years. I just had it all refone last year and had the Aux switch controled in line pump added with fuse and relay system. Works great. I would say you simple cannot expect to drive a GMC in hot weather today without an electric pump to feed the mechanical pump. It clears up instanly when you flip to AUX. Most erroneously concentrate on the fuel line from mech pump to Qjet, but that tubing has pressurized fuel making it resistant to boiling. The problem is before the pump as they are not good at moving vapor. If there is any porosity in your lines this problem is amplified. The old hose takes on "garden soaker" hose characteristics and must be replaced.
