Thanks for asking your question. I will try and help you out.
No. The engine does not require an external fuel pump. If it's sucking air. It can occur anywhere from the fuel tank to the fuel pump. But often I find them sucking air at the fuel filter or water separator.Please reply back if you need more help or have more questions. I am happy to assist.

Is there maybe a trick to locating the leak?Pressurising the system or something like that?
Sometimes they can be hard to locate. I like to bypass the lines and filter housings one at a time to find it. If you bypass something and it stops sucking air. You'll know it.

Last question-The problem not likely to be within the fuel pump itself?
Correct. Not possible for the fuel pump to suck air. Normally when they fail. The engine will not run at all.
