The early Transit's had a primer on top of the filter housing (as you describe). Later models deleted this. What you see on the new one is not a primer. It's a tester to check if you need to replace the filter. I've not waited that long to use it on mine...rather change the filter and keep it sweet anyway.

When you fit the new filter, make sure it's full to the brim with nice clean diesel. No primer I'm afraid, but if it was running nicely before, then it should start okay. Might be a bit lumpy until that air (if there is any) is purged. Light throttle at about 1500rpm should help.
