Product Description



We also have a limited # of blemished ones for sale. Click  ***HERE***

A central dump fuel rail for the KRX or KRX4 1000 is a must have in our opinion. The krx has been shown to have multiple fueling issues which has lead to the engine running lean on fuel and melting piston 2. Its a combination of a few very small things, which lead to a big issue.

We believe this central dump fuel rail is the final piece of the puzzle to finally cure the issues.  To learn more please watch the LONG video with lots of explanation and even an install at the bottom of this page 


Our fuel rail moves the inlet location to feed from the center unlike the stock KRX fuel rail.The stock one feed from the side This eliminates airation and low pressure issues.

Installation takes about 15-20 minutes
If you run a turbo or super charger this is a MUST HAVE 
No special tool besides push pin plyers are required. They can be purchased by clicking   ***HERE***    if needed. 

We highly recommend doing all 3 pieces of the lean running KRX puzzle. The roll over valve, fuel filters, and center dump fuel rail.
If you need our high flow fuel filters and roll over vent valve, you can add those at a discount in the drop down menu above.

    Highly impressed with the difference it made and the ease of installing it. Instantly noticed the engine was running so much smoother. Took the machine out for a 20 mile cruise and could tell a difference in the power. It seemed gain speed faster and and did not not take as much gas pedal to do so. I am new to this world of side by sides and having a mechanical background. I could not believe Kawasaki has not fixed this issue by now. But it is great to see Jake is passing on his knowledge of known issues and getting the fixes and making it available to us.

    Install was a piece of cake! I noticed 1st was the idle was smoother and quieter wasn't popping any more. Definite increase in power and piece of mind knowing #2 wasn't melting Also installed Jakes fuel filter and rollover valve as well as tweaking the float for more accurate tank reading Very happy with this purchase and Jake was right its a must have!
