But the engine temp is getting hot enough yeah?
Have you checked that the temp control on the dash is actually moving the little lever that lets water into the matrix? Bled cooling system? checked thermostat is working so hot water actually gets to matrix etc?
If you lie on the floor with your head on the pedals and look up, you should see a blue cable that's connected to a lever, above and to the left of the clutch pedal. That's the valve that controls the amount of water that gets into the matrix. All the way towards the bulkhead is hot and into the van is cold if I remember correctly. I only know this cos mine was knackered. I think the valve gets stiff as it heats up meaning the control get difficult to operate and then if it's forced, it kinks the control cables.
The little fuel pump is powered by the Eberspacher Heater but not the electric one on the bulkhead as far as I'm aware. There's no output from the heater to trigger it. Just the Diagnostic K-line, On/Off temp control line (not connected to anything in the vito unless you have v class parking heater) and the line that connects to the main loom that tells the heater the engine is running.
Other than the fuel pump, you don't need any of the other stuff on that ebay ad to make it work as long as you can bolt it to the chassis somewhere. There are a few on ebay now.
Do you now the heater you bought is a working one?
