Kawasaki KRX & KRX4 Billet Center Dump Fuel Rail (A Must Have)




Starting at: $159.99

Product Description



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. 


1- Billet aluminum center dump fuel rail with fittings

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.

    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!

    Ok, this is scary!!! After installing this. Fist my KRX idled much smoother, and my wife says it sounds quieter. The real fact is it had a better exhaust note from running smoother. first short ride the fuel felt a little fat to start and is was pooping on deceleration. That being said it felt like it had more power. by the end of the 5 mile ride it started feeling not as fat and stopped popping on deceleration. this tells me the computer is having to recalculate for more fuel to cylinder 2. it definitely has more power. Now the SCARY part. How lean was cylinder 2 running to get such a noticeable improvement???? This Part is a MUST BUY FOR YOUR KRX!!! Sam
