Blockoff fitting kits will allow the OEM in-tank fuel pressure regulator to be removed completely and replaced with a billet part which is necessary when installing an aftermarket externally adjustable fuel pressure regulator
The OEM in-tank fuel pressure regulator is fixed to maintain 40-43 pounds of fuel pressure at all times; for high performance applications where horsepower is boosted, it is necessary to install larger-flowing fuel injectors and be able to tune the fuel pressure up or down as needed
Most factory race teams are running 65 plus pounds of fuel pressure along with higher-flowing fuel injectors and externally adjustable pressure regulatorsthe R&D Fuel Pressure Blockoff Fitting is the answer to quickly replace and block off the port
The R&D fitting is manufactured to Deadhead or block the port solid
Kit for Kawasaki 310X is pre-machined and tapped and can be relief drilled to be able to install a Mikuni Super BN Series jet directly into the end of the fitting for a small in-tank restrictor jet which may be helpful for fine tuning fuel pressures in high-altitude situations where finer tuning of fuel pressure is necessary
