Performance Centerfeed Fuel Line Kit for Various Honda Models by Acuity

Whether you are trying to swap out your OEM fuel system for something more robust or just trying to tidy up your engine bay, this center-feed fuel line is as good as it gets. Not only is it compatible with both gasoline and e85, it also features our innovative quick-connect fitting for the firewall connection that makes installation a breeze compared to conventional nut-style fittings used on competing designs. Each hose features a reinforced rubber inner structure with a braided exterior that helps prevent cuts and abrasions to the hose. The 1/4" SAE Quick-Connect firewall side fitting features redundant seals for added protection against leaks, and the -6AN fuel rail side fitting will attach to any -6AN male fitting. For added peace of mind, we pressure test every fuel line after assembly to make sure all connections are pressure-tight. This line is compatible with virtually any K-Series fuel rail that has a center port (when used with an appropriate adapter). If you prefer a side-feed configuration on your fuel rail, this line can also be routed to the port on the side of the fuel rail closer to the gearbox. Since we are all about the fine details, each fuel line comes with a bracket that rigidly affixes the line to the backside of the gearbox to make sure the line isn't moving around during spirited driving or track events. The fuel line can even be unclipped from the bracket to make removal easy when you're servicing other parts of your car in the future. Trusted by pro-am racers and street enthusiasts alike, if you are looking for the best of the best for your car, this is the center-feed fuel line for your build.

Perfect for my dog
Color: Blue Puppy, Size: Medium Size 2
My dog (16 lb) LOVES to whip her toys around and throw them in the air to chase after them. This is the perfect toy for her to play outside by herself. I would repurchase for her over and over again if needed!

Pup loves this!
Color: Blue Puppy, Size: Medium Size 2
My pup loves his soccer balls. These are very durable although if you have a dog that doesn't grasp the concept of using the loops/straps to carry it, teeth could puncture it. They are a good value for the money if your dog likes to chase the ball, I get the smaller size ball for my dog (medium dog). They come with a pump but if you have a bicycle pump or a battery operated pump, it will fill much faster. Ours stay outside and even in the winter, they hold up well, just need a bit more air occasionally to keep it pumped up.

Well that didn't last long!
Color: Blue Puppy, Size: Medium Size 2
He loved it for the 15 minutes it took to destroy it! Cute design, but the material was thin enough to penetrate with his teeth and it was all over in a very short time! He still carries the carcass around and tries to play with it...it's sad. Definitely not for strong chewers.

Decent ball
Color: Blue Puppy, Size: Medium Size 2
Context: I have a busy, anxious Corgi. I like that it came with a pump to air it up. My dog likes the tag feature on it which made the ball easy to carry. She chewed off the tags pretty quick. She didn’t like herding this one as much. She prefers herding a basketball over this ball. The ball sits in the backyard through all the weather and elements and has held up pretty well. We’ve had it about a year and it’s still a good toy.
