Perkins M50 bleeding air--need advice

[Jan Geo]

When I bought my B41S5 a few months ago it started normally just a few seconds and would start up. It did blow wite smoke a little for 3-5 seconds-it has great power and uses very little oil.  Unfortunately I ran out of fuel on a trip to home dock. I got it running again but now takes 20-30 seconds grinding starter.  I also recently drained the 2 fuel filters (no water in them). I also added a low pressure cube 12 volt electric fuel pump.  Unfortunately it still takes 30 seconds grinding starter to start . Maybe my bleeding technique isn’t the best. Can the injector pump be bled.?  Advice please.  Thanks, George

Crack the injector lines at the injectors one at a time while running that should purge any remaining air in the system, or you may have picked up some crud in the line in the fuel tanks seeing you ran out of fuel

Jan,

crack the bleed screw on top of the fuel filter, work the lift pump till you can't see any air bubbles escaping. The Perkins can start instantly as soon as you push the start button. Here in the Midatlantic region I can start without using the glow plugs all season.
