There a couple of ways you can do it, but yeah I just go on the outlet and suck the fuel though, then reconnect pipes and start asap, may take a while on yours as it's probably drained back to the tank due to the time the fuel lines were open.  Just in case you don't know, the arrow on the primer shows the direction of fuel, the one way valve only works the correct way.

Once it does start, give it some throttle to keep it going and purge any air from the lines and filter.  

This is my setup on a 1.6TDCi Focus.

All sorted, borrowed a syphon pump & it started straight away, no more EML and the car can now rev over 2,000rpm & doesn't feel sluggish when accelerating.

Thanks for the help!
