K-Tuned Fuel Line Kits are now available for several of the newer Honda/Acura vehicles that have returnless style fuel systems. The 02-06 DC5 RSX, 02-05 EP3 Civic Si Hatchback, K-Swapped 01-05 EM2 civics all have returnless fuel setups that use special EFI fittings at all of the fuel related connections. For these chassis, K-Tuned has developed pre-assembled fuel feed line kits using lightweight black fuel hose and black anodized fuel fittings. These lines are designed to completely replace the ugly stock rubber fuel line all the way from the firewall to the fuel rail and will help to clean up the look of any engine bay.

The first connection is made at the firewall, using a special female EFI fuel adapter that properly adapts the factory hardline to a standard 6AN male fitting. Note that K-Tuned's special adapter fitting uses a threaded aluminum locking clip to ensure that the connection is secure and leak free.

This is the standard side inlet that connects on the left side of the rail and allows the use of K-Tuned's center fuel pressure gauge if desired and is sold separately. 

Vehicle applications: 02-06 RSX, K-swapped 01-05 Civic, 02-05 Civic Si

Durable and fun
Size: 4 Pieces, Size: 4 Pieces
I have a chewer who gets bored in the afternoon. She loves these Lego blocks. They’re sturdy enough for a big chewer and they hold her interest . She really enjoys figuring out how to get her breakfast!

Love the idea!
Size: 6 Pieces, Size: 6 Pieces
Love the idea of this product! Arrived 3/25/2026 and started using it the same day. Lab puppies (8 months old) loved it too, until one of the tabs was chewed off 😞 One of the puppies ate something (not this product) last week and was sick & finally threw up the rubber pieces he ate. So they can’t use the toys they love!

Get 8 pack for bigger / stronger dogs
Size: 6 Pieces, Size: 6 Pieces
This is the best puzzle toy i have found for my GSD mix. All around high quality product 10/10. Thick, durable rubbery material that holds up against a strong chewer. Individual pieces are big and bulky enough that i don’t have to worry about my bigger dog accidentally (or intentionally) swallowing a piece, so i don’t need to supervise. That being said, if you have a bigger dog or a strong chewer, i HIGHLY recommend getting the 8 pack if you actually want to keep them busy for more than 20 mins consistently. Bigger dogs just have more leverage to tug on the pieces because obviously…they are bigger, so its just easier for them. The more pieces you add and more tangled/thicker you can make it, the less leverage they have and the harder it is for them to get a good grip. I have a german shepherd/pitbull mix (big boi, v smart, v strong) and i initially got the 4 pack which, after the first few times, only took him about 5 mins to get all the pieces apart even with level 5 connections. So I ordered an additional 6 pieces (i have a total of 10 pieces now) so i could make it harder for him and it was totally worth it. Now I use 8 pieces with level 5 connections and vital essentials freeze dried beef liver treats inside for my GSD and it consistently takes him 30+ mins to get the whole thing apart. I have timed this lol. I can rebuild the 8 pieces multiple different ways to make it more or less challenging (but i always opt for as difficult as possible to keep him entertained for as long as possible) I use the other two pieces with a level 1 or 2 connection for my other dog- bordercollie mix who is not a very strong chewer, he mostly just rolls it around/ licks it until it finally opens or i help him. Both of my dogs are obsessed with this. And i love watching them try to figure it out.

Awesome Tough Chewer Focus Puzzle
Size: 8 Pieces, Size: 8 Pieces
Our 2 yr old busy Mini Goldendoodle (24lbs) looooves this! The material is super tough, yet malleable; he has chewed away and you can’t even tell. We got the 8 pack, worth it! I load them all up with mostly kibble and a treat or two. It took just a short time for him to figure out how to really get it apart. On 1 it came apart really easy for him. We are mostly on 3s, with 2s. When he gets down to only 2 pieces connected it’s usually a 3 and it takes a little longer to get apart due to less leverage. It is mostly easy to use but the higher the plug end is, the more effort it will also take for YOU to get it together. The numbers are a little hard to see, more so on the yellow over the blue. If you use kibble like me, don’t fill it too full as then it won’t connect fully and be prepared for kibble to fly everywhere when they finally get it off. There are holes in the plug part, if you put something in it like peanut butter, remember to poke the holes out! Eew! Other than that they are fairly easy wash out in the sink! Overall, this has become our go to, extended focus, quiet time, [essentially a] slow feeder!
