I'm not sure whether they were press fit or cast in place. My money 
would be on the former. At any rate, it worked for well beyond the 
design lifetime, so it's not surprising that some of them 
occasionally come loose after 40 years.

Even now, most of them are fine until excess stress is applied to the 
fitting. Sometimes this is the weight of a fuel filter and sometimes 
it's careless tightening of a hose clamp.
