757 Fuel Pumps
Everyone thinks they know where the 757 Fuel Pumps are located because of how similar the 757 and 767 are. But if you really boil it down, do you know? This video sheds a spotlight on that very question. https://youtu.be/3LTA6mfsytk

🚨 Welcome to GSI Guy Training 🚨
If you’re here, you care about understanding aircraft systems beyond the rote memorization. This community exists for one reason:👉 To make complex aviation systems clear, practical, and usable in the real world. Whether you’re: - A new hire trying to survive initial training - A seasoned pilot or maintainer sharpening your systems depth - Someone who’s tired of “because that’s how it is” explanations —you’re in the right place. What this community is: ✈️ Clear, no-nonsense breakdowns of aircraft systems ✈️ Real operational context (why things work, not just what they do) ✈️ Scenario-based thinking you can actually apply on the line ✈️ A place to ask questions without getting roasted (well, maybe slightly roasted 😁) What this community is not: ❌ Death-by-PowerPoint (We will try not to anyway 😬) ❌ Pure memory drills with no understanding ❌ “Just trust the book” answers Here’s how to get started 👇 1️⃣ Introduce yourself below: Aircraft / background Current role or goal One system that’s always been a pain to understand 2️⃣ Jump into the pinned postsThat’s where the core resources, breakdowns, and upcoming content live. This community will grow with your questions, your pain points, and real-world issues you want explained. Glad you’re here.Let’s build real understanding. — GSI Guy ✈️💡
