I've found one way to eliminate all the fuel transfer (lines, fittings,
valves, tank, etc) agony is to arrange an IV drip with a jug of diesel
suspended well above the engine, and start a syphon, or just  set it up like
a hose bag, so gravity will "push" the fuel into the pump, assisting the
vane pump, and squirting fuel out through the leaks that let the air in,
identifing them.
I used this method to prove my pump shaft seal was so dry and worn that fuel
squirted out around it when the fuel was fed by gravity.
Sucking is fraught with peril, it's better to blow.
