We RIPPED OUT our WHOLE Fuel System-Then Built Our Own

In this episode, we tear out the entire fuel system from our 78' aluminum trawler as part of our massive Cummins 6.7 marine repower. What started as an engine swap has grown into a full-on systems overhaul-including custom fuel lines, filters, transfer pumps, and return systems. After removing our two Detroit Diesel 12V71s, we realized it didn't make sense to keep the old fuel setup. So Blaine got to work designing a new marine fuel system from scratch-tailored specifically for the Cummins engines and our unique liveaboard needs. We'll walk you through the old system's removal, what didn't work anymore, and what we're building to replace it. From marine-grade hose routing to mounting new filters and transfer components, this is a deep dive into boat fuel systems, designed with simplicity, access, and reliability in mind. Whether you're upgrading your own diesel engines, planning a refit, or just like watching hands-on marine engineering, this is a key step in the journey. Follow along as we get one step closer to launching our new engine room. #Cummins #DetroitDiesel #BoatRefit ?
