The fuel rail supplied with this kit is durable Nylon that will not corrode! No more stuck injectors, no more corroded aluminum, and benefit from near perfect fuel metering to each injector. Comes with the adapter plate, Nylon fuel rail, all SS hardware required, Fuel line and aluminum spacers.)

Fuel Pressure Gauge

(Fits all models. Made to fit no modifications required, plug and play for tuning of all sorts or checking for correct fuel pressure. Disconnect when tuning is complete or leave on for tuning on the fly. Digital fuel pressure gauges have a sensor and gauge. For 250/260 models this is mounted on the fuel rail, for 300/310 models a manifold is included for inline mounting. All necessary hardware is included with instructions, kit comes with both setups.)

Kawasaki Quick Connect Fuel Fitting

(Fits a variety of Kawasaki motorcycles to watercraft. Made for use with all fuel types and works with most applications requiring no modification. For use with Kawasaki Ultra's, the fuel rail fitting will need to be changed to the below fitting, since the stock one is a bit long for these.)

KP HT Fuel Rail Fitting

(Fits all models with a plastic fuel rail (300/310/SXR/160). Made for racing applications, or high boost applications requiring high fuel pressures. For stock applications as well, stock fitting can break causing down time. Upgrade now! Made of 316 Stainless Steel. Proudly made right here in our shop, with locally sourced Stainless Steel.)

$112.99

Fuel Line

(Fits all models. KP Fuel line can be made in any length and is rated for a much higher pressure than OEM. Also rated for any fuel including E-85. Fittings on 250/260 fuel rail must be upgraded to our smaller higher flow fitting. Can be made to any length. Standard length is 18 inches. Comes with one quick connect fitting (Green).)

Kawasaki High Flow 10 Micron Fuel Filter

(Fits modified and stock machines. Will prevent clogging of fuel injectors which will lean out your AFR and reduce performance. Remember, whatever is in your tank gets sucked up (Kawasaki only has a mesh bag at the bottom of the tank)! Fuel filter is replaceable, comes with attached fuel line and additional crimp clamps. Will fit 250/260/300/310/Ultra LX/15F/SXR models. Comes with clear installation instructions.)

Fuel Pump Replacement

(Fits all Kawasaki models. If you would like us to install the new pump, please ship us your old pump with your information. 320 LPH fuel pump is for all high performance applications including E-85, race fuel, nitro, methanol etc. Capable of fuel pressures exceeding 100 PSI. This is a direct fit, no cutting or fabrication required. We recommend using our KP-Aeromotive fuel pressure regulator with this pump. All R&D fuel pumps require permanent modification of your fuel pump housing, this not only ruins your housing, but weakens the bracket that holds the pump in! KP keeps the fuel pump upgrade easy and simple! 250 LPH Fuel Pumps come with PTFE shrink tubing, wire harness, and spare o-ring.)

Adjustable Fuel Pressure Regulator

(Used on 250 and 260 jet skis with KP Super Boost pulleys, cams or port and polish and 300/310 KP booster pulleys, cams, or port and polish. Used on 15F/SXR/Ultra LX for additional fuel on race machines. KP-Aeromotive can be used as a rising rate or standard fuel pressure regulator. The KP-Aeromotive fuel pressure regulator comes with all hardware you will need, including high pressure fuel line, clips, clamps, vacuum line and more to make for an easy installation. The regulator is mounted as close to the pump as possible and insulated, so the fuel absorbs as little heat as possible. Which is important in racing conditions. The regulator will hold fuel pressure even when the pump is off, which is very important. Also, it holds fuel pressure extremely steady to avoid dips and irregularities in fuel delivery and AFR. This will work for all setups from stock, to stage 6 to Nitro to a port and polished high flow machine. The R&D fuel pressure regulator can be used as a stand alone or rising rate. Comes as you see, no additional hardware.)
