Pump that primer pump LOTS! When I changed out my spin-on filter I filled it with diesel, AND pumped the primer pump 100 times for good measure (it builds character!). You may also need to replace your primer pump if doesn't seem to be pushing fuel through the system (if your fuel tank is low enough ask a friend to listen back at the fuel fill pipe after removing the filler cap - you should hear the excess diesel sloshing out of the return pipe and falling into the tank).

Also, I believe that you'll hear a 'squirt' noise from the bypass valve (as opposed to the sound of the primer pump).

Once you've got fuel in the low pressure side of the system, then you're still gonna have to do the cranking with the fuel injector lines cracked thing to get the air out of the high pressure side of things before it will start.
