On some newer model Honda and Acura vehicles you might notice that Electronic Fuel Injection (EFI) style fittings are being used on several of the fuel system components. Typically these are found a bit more often on returnless fuel systems and more specifically on the fuel rail, fuel feed (firewall) hardline and we've also seen them used on some fuel pump hangers. These special adapter fittings are designed to quickly adapt a male EFI connection to a male 6AN fitting. This makes converting EFI parts to a custom AN fuel system very simple.
The OEM design is held in place with a standard plastic locking clip. We also offer a special design with a thread on locking clip. Both of these adapters use an internal dual o-ring seal to ensure connections are leak free even under high pressures. We have used the 1/4" adapter on RSX and 8th Gen Civic fuel feed (firewall) hardlines and the 5/16" adapter fits all of the stock EFI K-Series fuel rails we have seen so far.
If you want to measure and confirm what size EFI fitting you have, simply check the line thickness with a 1/4", 5/8 or 5/16" wrench.

Blue ball, my dog likes blue.
Just a ball right? Evidently not! My dog won’t chase an orange chuck it ball or the glow in the dark ball- only the blue one 🤷🏼♀️

Love this set!!!
Size: Medium (2.5"), Style: Fetch Pack 1
I was trying to figure out which of the many different balls this company offers, and I was getting frustrated but then i was SOOOO happy to see they had multiple sets that had multiple of the different balls they offer!! I bought this set and the other set they offer, but this one was my favorite and I think my dogs too! The orange ball works great and bounces just high enough that it doesn’t clear our patio wall, but enough for him to go and jump up to retrieve. But the glow in the dark ball is his favorite! Both me and my pomsky were blown away how we brought the glow in the dark ball outside just as the sun was going down, and when we brought it back inside it was BRIGHT AND GLOWY!!! Even with the sun going down and not much light left!! He loves to play with it in the house after it’s all glowy from the sun. Sometimes we even glow it up under a light inside the house if it’s dark outside, and he will play with it outside in the dark haha he loves it!!! And I think it’s pretty cool too!! All of the balls this company overs are VERY durable! We realized early on that we cannot give our dog regular tennis balls cuz his favorite thing to do is tear the outside fabric off!! So we were trying to figure out what company has the best balls for dogs so they can’t sit there and try to pry them apart, and we found this company!! We have already bought from them about 3 times and all of their balls are durable and bounce how they say they will bounce!! They have the super bouncers and the glow in the dark one and the one with angles that will bounce in different directions and the ones you can throw REALLYY far! Overall, all the balls from this company are very durable, bounce really good, and keep my dog occupied without allowing him to sit there and tear it apart!!! Which i love cuz I do not like when he stops playing with us to sit there and try to take off the fabric, cuz then he could swallow it! So always buy the balls from this company!!! They are the best and most durable!!!! Also plenty soft for your dogs mouth so they can chew on it a bit and it won’t hurt their teeth/gums!

Good sturdy balls
Size: Medium (2.5"), Style: Fetch Pack 2
My dogs love balls! Unfortunately, they tend to chew them up very quickly. My Belgium Malinois chews on this all the time, and it has held up pretty well. Good option for chewers
