6. (SKIP - for gravity fed Pumps
w/plenty of fuel) Check for Air Leaks:
Check all fittings from the pump back to
the tank for suction side air leaks (make
sure pipe sealant is used for all threaded
connections). Inspect for cracked flares,
tighten fittings and look for cracked
lines. If you see no evidence of leaks,
try soap and air pressure test on the
suction side lines by pressurizing at the
inlet through the 3/8 inch copper line
that leaves the fire-stop valve at the
tank.
