We set out to build the ideal K-Series fuel rail that will work for everyone from the bolt-on K-swapped street car to a 2000+hp methanol monster like our Outlaw car. The SpeedFactory Billet K-Series Mega Flow -10AN Fuel Rail is the result!
Our Mega Flow rail features a GIGANTIC 0.806” fuel bore with -10 ORB inlet/outlets and Viton O-rings. Perfect for high volume ethanol & methanol fuels, and the large internal volume helps dampen the pressure pulses created by the massive fuel injectors now commonly being used.
Three (3) -10 ORB ports allow user the option to feed or return from the ends OR under the center of the rail for a sleek, tucked look.
Vehicle Application/Fitment: All K-swapped ‘88-‘00 Civic / ‘90-‘01 Integra chassis and any universal K-swap applications. Fits most K-Series engines except direct-injection K20C and K20B engines. Fits RBC, PRB, and RBB intake manifolds and almost any aftermarket intake manifold.
Product Features:
- Precision CNC machined from 6061-T6 billet aluminum
- Black Anodized finish throughout adds durability & eliminates corrosion
- Laser-etched SFR logo
- -10AN ORB Inlet/Outlet ports with massive 20.4mm (0.806”) fuel bore supports even the most demanding 2000+hp turbocharged setups on high volume alcohol-based fuels
- Center feed/return port for tucked fuel line routing if desired
- One (1) 1/8 NPT port for fuel pressure takeoff option (example: gauge, sending unit, or wet nitrous feed) and includes one (1) Stainless Steel 1/8 NPT plug
- One (1) additional M6x1.0 threaded hole that can be used for mounting bracket (example: EBC solenoid, wiring d-ring, etc)
- Includes two (2) Stainless Steel M8x1.25x25mm socket head cap screws for fuel rail mounting & one (1) -10 ORB Male to -6AN Male feed fitting and two (2) -10 ORB Port Plugs for use with your commonly seen -6AN fuel system setups.
NOTE:
- Always make sure to thoroughly flush out any new fuel system components before use to make sure you do not get debris into your fuel injectors.
- Always check for fuel leaks before starting the engine.
- Replace all crush washers, o-rings, cushion rings, seal rings, and insulators when fuel rail is disassembled.
- Different combinations of fuel injectors, adaptors, and intake manifolds require various spacers/adaptors/o-rings/etc for proper installation. This is a normal part of setting up your fuel system and you will need to figure out the appropriate parts for your specific combination.

Finally found my endgame mouse
Color: Classic Black, Color: Classic Black
Finally found my endgame mouse — perfect for lightweight lovers and RTS gamers.
I've gone through a lot of mice over the years — office mice, productivity mice, various gaming mice — and I kept running into the same problem: they were either too heavy or too bulky for my taste. The Orochi V2 is the first mouse where I thought, "this is it."
The weight and size are just right if you prefer a light, nimble feel in your hand. It doesn't fatigue your wrist over long sessions, and the compact form factor gives you great control without feeling like you're pushing a brick around your desk.
If you play StarCraft 1 or other real-time strategy games that demand fast, precise movements, I genuinely think this is one of the best options you can find on Amazon. The responsiveness and accuracy make a noticeable difference when every click counts.
Battery life is also excellent for a wireless mouse, and switching between Bluetooth and the 2.4GHz dongle is seamless. Overall, this is the mouse I keep coming back to — and I don't see myself switching anytime soon.

Very glitchy mouse won't accept clicks, made me reinstall windows
Color: White
TLDR: Ask ChatGPT about this mouse and it'll tell you that other users have reported issues with this mouse not clicking properly. It will tell you that this is a known issue with this mouse.
So I'm an IT expert (programmer, been using PC's since Windows 3.1). And I could not get this mouse to work right. The mouse doesn't work right when the computer goes to sleep, and then wakes from sleep. This problem occurs on Windows 11 pro.
When the mouse is connected in Bluetooth mode: First problem is, the mouse will NOT reconnect to the PC when the PC wakes from sleep, unless you have "Show notifications to connect using Swift Pair" disabled in windows Bluetooth settings. But setting is on by default. Second problem is, even with this setting disabled, and even if the mouse successfully reconnects when the computer wakes up, the computer will NOT accept clicks when it wakes up. This mouse apparently drops a phantom click that it never releases. The only way I could find to get rid of that phantom click is by pressing CTRL+ALT+DEL every time the computer wakes. This resets the phantom click and the mouse would function normally. But it's super annoying to have to press CTRL+ALT+DEL every time the PC wakes, especially since this mouse is supposed to be a gift to my little girl, I don't want her to have to deal with it not working perfectly. Also the mouse would sometimes stop accepting clicks even in the middle of playing games, but this only happened rarely in Bluetooth mode.
On the wireless USB mode: The mouse cursor is NOT visible when windows first boots. You can't use the mouse to get to the box to type your PIN number to unlock the computer. You must use the keyword to get into windows, and then the cursor appears. This problem doesn't happen when using the mouse in Bluetooth mode, only in the wireless USB mode. And then the phantom click issue is MUCH more frequent in the wireless USB mode, and doesn't require the computer to wake from sleep, but happens randomly even in the middle of playing games... suddenly you can't click anything. And when waking from sleep, or when the mouse "goes to sleep", when it wakes up there's issues with clicks... and sometimes the cursor isn't even visible.
Connecting a second mouse: When the computer stops accepting clicks, then even the second mouse would not be able to click. All connected mouses would stop being able to click. But this problem of not being able to click, would ONLY occur if the Razor Orochi V2 mouse was connected to the computer either via Bluetooth or wireless USB. If I disconnected the Orochi V2 mouse, then the problem never happens. So it's definitely this mouses's fault.
But initially I didn't realize this mouse was the culprit. Because it affected all connected mice. So I thought, at first, that it was a windows issue... maybe a bad driver I had installed in the past. So I ended up reinstalling windows, trying to fix any potential driver issues. It wasn't until after that, when I discovered that the problem was this mouse all along. I was super upset to have reinstalled windows, and lost all my software and settings, only to then discover that the problem was still there and it was this mouse all along.
As for getting my money back, amazon did not offer me an option to return the mouse and get a replacement. It only lets me send it back for a full refund. No option for replacement. So I think I bought this mouse when it was on sale. So it seems like they are expecting me to send it back, and then repurchase it at the new higher price, if I want to try it again. It's possible mine was simply defective.
I did every imaginable thing to try to get this mouse to work. The mouse I had was brand new from Razor, but it was running an old firmware. I did a firmware update to version 1.03.00 (it was running version 1.02.00 when it arrived). I can confirm that firmware update did NOT fix the problem with the phantom clicks.
I also set all the related devices in my device manager to not go to sleep, including the USB slots. That did NOT fix the problem with the phantom clicks.
I also, at the advice of chatGPT, did a bunch of registry edits, none of which fixed the problem.
I also, at the advice of chatGPT, wrote my own c# application, which attempted in various ways to force the mouse to release the phantom click, at least when the computer would wake up. I was trying to mimic the behavior of pressing CTRL+ALT+DEL. After many hours of coding, I was unable to programmatically correct the problems with this mouse.
I really wanted this mouse to work because it's wireless, and its small, so it fits my daughter's hand.
I'm now having to return this mouse at my time and expense, no option for replacement, lost whatever discount I got from the previous sale, and I lost days of my life trying to fix this mouse, and I lost some of my software and settings from the reinstallation of windows, so I have work to do just to get my daughter's computer back to normal again. Terrible experience.
Conclusion: Ask ChatGPT about this mouse and it'll tell you that other users have reported issues with this mouse not clicking properly. It will tell you that this is a known issue with this mouse.

Perfect mouse. Period.
Color: Black and Gold, Color: Black and Gold
LOVVVVEEEEE this mouse!!!! 20/10. I bought this for my new laptop and it was such a great value. I fell in love with how smooth and sleek it is, and how incredibly QUIET it is! This is the main reason I bought it, for the silence and the fact that it doesn’t click click click. So I immediately bought one for work since the one I have at work is so loud and clackety. Game changer. These are amazing. Love how they look, love how they feel in my hand using them, love how they work when using a computer, love how they fall asleep and save battery when not in use, love how they don’t make clicking noises or scrolling noises. Sooooooo good!!! Oh and love the price.

Very durable and pretty 😍
Color: Mint Green to Purple
The purple-mint gradient color is so pretty. It works well and feels nice in my hand. The buttons don't make a lot of noise, which is a bonus. Good for the price and haven't had any issues yet. You only need one battery and it lasts a long time. Installation is easy, just plug in the USB receiver, switch the button underneath to ON and you're good to go. No Bluetooth needed.
