After soaking boat fuel system components in E-10 ethanol vs. Rec 90 non-ethanol gas for 17 months, the results expose severe hidden damage. While metal parts, pumps, and injectors show minimal impact, E-10 fuel completely distorts rubber O-rings, delaminates fiberglass, and cracks epoxy like JB Weld. Most shockingly, common blue and gray fuel lines suffer catastrophic internal liner collapse, turning fuel pitch-black and threatening total engine failure. Watch as these real-world teardowns reveal which hidden boat parts are ticking time bombs!
