Mark,
I made all my hoses: fuel, oil, hydraulic, brakes and maintenance equipment. The fuel lines are good old Aeroquip 303.  All were pressure testing using a home-made flow and pressure tester first described in the the LNN.  It is a cross where one leg attaches to a garden hose and has a valve, the second leg has a zerk fitting for pressurization, the third leg has a pressure gauge, and the fourth leg attaches to the hose under test.
Whatever hose you choose make sure it has a metal wire braid, either internal or external, so that fluid flow cannot build up a static charge.  I know of one aircraft fire traced back to a fuel line with no electrcal conductivity.
