Chasing a fuel leak on a 737 for 8 hours then finding it was just a loose clamp

I spent a whole shift tracking down a slow drip from the fuel manifold, swapped seals and everything, only to find a clamp that was barely a quarter turn loose. Is it better to methodically check the simple stuff first or just dive into the hard work right away?

...but I kinda disagree with just tightening every clamp you see. That approach works until you miss the real problem because you're too focused on the easy fix. I've been burned going the other way too, like that time I spent three hours chasing a bleed air leak that ended up being a cracked weld hidden behind a bracket. You can't fix that with a screwdriver. The trick is having a solid mental flowchart you run through before you touch anything. Look at the drip, think about what makes sense based on where it is, then start with the quick checks that match that spot. It's about being systematic, not just lazy or eager.

...and that's exactly the kind of thing that makes you want to throw your toolbox across the hangar. I swear, the hangover from the time I spent replacing a whole fuel line on a King Air is still with me, and guess what? Loose clamp again. You gotta laugh or you'll cry, man. It's like your brain wants to prove you're a real troubleshooter by diving into the hard stuff, but the plane's just sitting there laughing at you with its stupid little simple fix. Next time I see a drip I'm just gonna stare at it for a minute and tighten every clamp in sight before I even touch a seal.
