Aeromotive Universal Fuel Pressure Regulator Injected Return Style. 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. 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.
