Don't intentially run out, you can stuff your pump if you try to switch tanks after you run out, while still in gear driving the motor down the highway, with no fuel in the pump.If you do run out, then open the bonnet and pump the primer on top of your filter continuously until hard. Then wind the starter (and if possible if you have someone with you) continue pumping the primer plunger and the engine will start. If no one is with you, pump until hard, give a 5 second crank, pump again etc. There may be a better way if you can get the plastic plug out on the pump cover, as there may be a bleeder under it, but I tried on the side of the road and couldn't get it out. However, if you could bleed to the pump in the usual way if there is a bleeder under the cover you will have no troubles. If you have a pair of pliers, take the fuel outlet hose off the filter, and pump until the filter is full and fuel is flowing, then put the hose back on and pump again until hard etc. This will make starting easier. I hope to pull all the covers off soon to get a look at the pump and see if there is a bleeder there somewhere.
