Most Universals (and later Westerbeke) diesels will have an electric lift pump. Yours is quite likely a "Facet" brand, altho repainted by Universal.
Unless you have a miniscule air leak in the gaskets when you screw the Racor back together, you should be able to turn on the engine circuit with the key, hear the pump click continuously as it pumps (over the obnoxious buzzing from the low-oil-pressure buzzer), and literally watch the fuel level rise inside the filter bowl. After a minute or so the fuel will then fill the line, the spinn-on engine filter, and then start splashing into the tank via the return line.
At which point you should be able to start 'er up.
Those little Racor's are kind of fussy sometimes about getting both gaskets sealed. I have had one fail and it gave me fits to finally trouble-shoot the problem.
To speed up the fuel purging process I have sometimes poured diesel back into the filter assembly (from the can I drained it into to start with), and sometimes not.
Let us know how it goes, and if this has not answered your questions, ask again! These little diesel engines do not need much to start and run... except fuel!
