It's EPA and CARB compliant, rated to 100 PSI, and reinforced to hold its shape under suction. This is the black feed line you run from the tank through the filter to the engine on outboards and small inboards.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sierra Marine 16-368-0385 is a 3\/8-inch inside diameter low permeation fuel feed hose built for the fuel supply side of your boat's system. It's the black, reinforced hose that carries fuel from the tank to the filter and on to the engine, and this A1-15 rated version is made to hold up to ethanol-blended pump gas without letting vapors weep through the wall. You get a full 25-foot coil, enough to handle most tank-to-filter runs on a trailer boat or a small center console with length to spare.\u003c\/p\u003e\n\u003cp\u003eLow permeation is the whole point here. Older fuel line let gasoline vapor pass right through the rubber, and on a boat that vapor ends up trapped in an enclosed bilge where you can smell it and, frankly, where you don't want it. This hose is EPA and CARB compliant, so the wall is engineered to keep those vapors inside the line. If you've ever popped a hatch and caught that heavy fuel smell, upgrading the feed line to a compliant low-perm hose is one of the simplest fixes there is.\u003c\/p\u003e\n\u003cp\u003eThe dimensions are straightforward. 3\/8-inch ID, 0.68-inch OD, rated to 100 PSI maximum. That 3\/8-inch size is one of the most common fuel feed diameters on outboard rigs and smaller inboards, so it drops right into a lot of existing routing. The reinforced polyester braid inside the wall is what lets it hold its shape under suction, which matters on the feed side where the pump is pulling fuel through the line. It won't collapse on you when the engine's working hard.\u003c\/p\u003e\n\u003cp\u003eThe black cover isn't just cosmetic. It stands up to the sun, fuel, oil, and salt air that live in an engine compartment, and it won't go brittle and chalky the way cheap hose does after a season or two exposed. This is hose built to sit in a working marine environment and keep doing its job.\u003c\/p\u003e\n\u003cp\u003eWho's this for? If you're re-rigging a 20 to 25-foot center console, replacing tired fuel line on an older outboard, or cleaning up a fuel system during a tank job, this is the feed hose you reach for. The 25-foot length covers a tank-to-filter run with margin, and having extra on the coil means you can make clean routing choices instead of stretching a short piece tight. Measure your actual routed path first, though, including the bends, before you cut.\u003c\/p\u003e\n\u003cp\u003eA few install notes from the dock. Use double stainless clamps at every connection to meet ABYC fuel system practice. A single clamp on a fuel joint is asking for trouble, and doubling them is cheap insurance. Support the line about every 12 inches along the run so engine vibration doesn't chafe it against a bulkhead or a bracket over time. And where you've got a tight bend, say around an engine bed, don't force the hose into a hard kink. Use a proper elbow fitting instead and let the hose take a gentle sweep. A kinked feed line restricts flow and eventually cracks.\u003c\/p\u003e\n\u003cp\u003eFor fittings, pair it with 3\/8-inch barbed connectors rated for 100 PSI. Brass or quality nylon barbs are the way to go. Cheap plastic barbs can crack under pressure and they're not worth the risk on a fuel line. Push the hose fully onto the barb, seat your double clamps behind the barb ridge, and you're set.\u003c\/p\u003e\n\u003cp\u003eOne honest note on service life. Even a good low-permeation hose doesn't last forever. Ethanol in modern pump gas slowly works on the inner liner, and after several years, especially on an older boat that sits, it's smart to inspect and plan on replacing the feed line during your next tank cleaning. This hose stiffens a little in cold-weather installs too, so if you're rigging in the cold, let the coil warm up first and it'll route a lot easier.\u003c\/p\u003e\n\u003cp\u003eBottom line, it's a no-drama replacement fuel feed hose that does exactly what a marine feed line should. Compliant, reinforced, correctly sized at 3\/8-inch, and long enough at 25 feet to do the job right the first time.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e3\/8-inch inside diameter and 0.68-inch outside diameter, sized for the most common marine fuel feed runs so it drops into existing routing\u003c\/li\u003e\n  \u003cli\u003eA1-15 low permeation construction keeps fuel vapor from weeping through the wall, cutting that heavy fuel smell in enclosed bilges\u003c\/li\u003e\n  \u003cli\u003eEPA and CARB compliant, so it meets current emissions standards for marine fuel lines\u003c\/li\u003e\n  \u003cli\u003e100 PSI maximum pressure rating handles engine fuel supply duty on outboards and small inboards\u003c\/li\u003e\n  \u003cli\u003eReinforced polyester braid holds the hose shape under suction so the feed line won't collapse when the pump is pulling hard\u003c\/li\u003e\n  \u003cli\u003e25-foot coil gives you enough length for a full tank-to-filter run with margin for clean routing\u003c\/li\u003e\n  \u003cli\u003eBlack cover resists sun, fuel, oil, and salt air without going brittle in the engine compartment\u003c\/li\u003e\n  \u003cli\u003eFuel feed rated, the supply-side hose that carries fuel from the tank through the filter to the engine\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sierra Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size is this Sierra fuel hose?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 3\/8-inch inside diameter hose with a 0.68-inch outside diameter.
