Gasoline Fuel Injectors & Seal Kits


GB’s line of remanufactured OEM fuel injectors are remanufactured using a proven 15 step process at our state of the art facility in Long Beach, California. GB is the only remanufacturer with the ability to replace internal injector coils, injection mold new fuel injector bobbins, and wind them to OEM specifications. When necessary, new connectors are molded on the injector which are color matched to their OEM specifications. In many cases, GB's engineering team can improve on the OEM design by eliminating the original failure mode. 


For example, GB's engineers solved a common failure on a Nissan/Hitachi injector that suffers from a materials defect with the OE design. On these injectors, the enamel insulation on the injector coil breaks down over time, resulting in electrical failure of the injector. The solution? GB's design team developed a remanufacturing process to replace the internal electrical coil. This involved molding new bobbins, using higher temperature enamel on the new coil winding, encapsulating the coil and remolding a new connector on the injector.

  1. The injector is completely disassembled. The original coil, o-rings and seals are discarded.

  2. New coil bobbins are wound with upgraded wire and enamel. New coils are over-molded to encapsulate the coil.

  3. The new coil is installed with new o-rings and seals. The injector is over-molded with a new connector and electrical terminals.

Once remanufactured, each injector is 100% tested under multiple operating conditions to ensure it meets or exceeds OE specifications for flow rate, spray pattern, coil resistance, form, fit and function. Each injector includes new external seals and o-rings. Where required, an application specific technical bulletin is included.

GB also offers a complete line of injector seal kits. Each seal kit includes the necessary o-rings and seals to properly reseal the injector, which is a recommended practice any time the injector is removed. Each kit services one injector and includes hard to find or previously dealer-only components.
