The instruction for the vaccum pump procedure is with a bleeder screw installed at the return line, using a vaccum pump, one draws the fuel through a hose immersed in a container of fuel and as you vaccum the fuel through the system you watch for bulbs, if now showing you stop vaccuming and watch to see if you have flow, with the thought that the fuel tank is higher than the engine. Using this procedure I find 90 percent of the faults. There was once when this really didn't work well and knew there was a leak so I introduced a die, same as we use in airconditioning, and with the use of a black light was able to find a crack in the fuel pump body.
