If you're looking for a solid hose that can take the heat—literally—check out the HPS 5/16-inch (8mm) ID silicone hose. This isn't just any silicone hose; it’s got a special fluoroelastomer (FKM) liner that makes it tough against the nasty stuff like gasoline and diesel, which is a game changer for anyone who’s serious about their ride.
At 8 feet long, this hose is perfect for a range of applications. Whether you're dealing with fuel return, crankcase ventilation, or even turbo oil return, this hose has got you covered. The FKM lining means you won’t have to worry about it degrading over time like standard silicone hoses do. It really stands up against high temperatures, too, with a range that goes from -65°F to a scorching +350°F (that's about 177°C for those who like to keep it metric). And with a maximum working pressure of 55 psi for fuel lines and 90 psi for other uses, you can trust it won’t let you down under pressure.
Now, let’s talk specifics. The hose has a 5/16" inside diameter and a 5/8" outside diameter, with a wall thickness of about 4mm. That means it’s well-built but still flexible enough to work with tight bends—just a 1-1/4" bend radius. You can snag it in black or blue, so you can match it to your engine bay or just go for that pop of color.
But hey, a couple of things to keep in mind: don't push it over 55 psi if you're using it as a fuel line, and steer clear of using it for continuous alcohol fuel. Also, it’s best not to fully submerge the hose in fuel while it’s in use. Just a little heads-up to keep your setup running smoothly.
In short, if you're in the market for a reliable, high-temp hose that can handle the tough stuff, the HPS FKM lined silicone hose is a solid choice. It’s rugged, versatile, and built to last—just what you need for your performance projects.
