When pumping the primer pump, the sound will noticabley change when fuel actually starts making it to injectors. It does take a while though.

If it doesn't seem to be doing it, even after LOTS of pumping, or if you see leaking around the primer pump, it may need to be replaced. There is an 'old version' that has a round white knob on the pump handle, and a 'new version' that has a black round cylinder as the main pump handle. If its the old version, and doesn't seem to be 'doing it' for you, then you may need to replace it. Its easy and cheap.

peace,
sam
