* NPT tapered threads require Teflon (PTFE) tape and /or sealant to properly seal. Moderate tightening force is required. Do not attempt to over-tighten or bottom out the threads. Use a proper fitment hex key to tighten the 1/8" NPT plugs. A lose fitting hex key will damage the fitting.

The Racetronix REG-G7B1 regulator is made from CNC machined billet T6 6061 anodized aluminum for maximum reliability and corrosion resistance. The dual-layer fiber-reinforced diaphragm is compatible with gasoline and E85 fuels. To reduce boost/vacuum leaks we have incorporated an o-ring seal under the pressure adjustment screw. There are three boost/vacuum ports on this regulator, one on the top in the factory location and two on the sides. This allows the regulator to be configured in the factory fashion using the top vacuum/boost port or using the 1/8" NPT side ports for alternate boost line configurations or sensors. Plugs are included to block off all unused vacuum/boost ports both top and sides. A 5/32" hose barb is included if one wishes to use one of the side ports. The front 1/8" NPT fuel pressure port can be used to mount a fuel pressure gauge or sensor. Two sets of screws and standoffs are included for mounting the regulator on factory or common aftermarket fuel rails (i.e. Champion).

When using the boost/vacuum side ports we recommend our ADF-481603 adapter, -3 PTFE hose and fittings to be run to your reference port or vacuum block. Racetronix does NOT recommend the use of Nylon push lock brake hose fittings PERIOD!
