You're right of course, that millions of cars are working just fine with barbs.  Mazda even uses those annoying spring clamps.  As much as I hate them though, I have to admit that none were leaking when I threw them away.  

As for not worrying so much about the inlet side, I'm not sure I agree.  There's quite a bit of potential suction on that fitting, though it shouldn't normally be that great.  It's easier to suck air in a loose fitting, than push fuel out, and air bubbles in your fuel lines can make for an evil problem to diagnose.   If I had a pump in my hand that gave me not option, I might use the barb, but I'd never do it when I had the option of using an AN fitting.  

No right or wrong answer, just my personal preference.  

Cheers,
Rusty (OK, so maybe I will do the Airbike...)
   

You just want me to spend more money that I don’t have :). All my fuel filters and fuel pumps are below tank level, so there is not much suction, but gravity fed. Have you seen Finn’s fuel lines? He is my hero.
