The Racetronix REG-FI666 regulator's high flow design is recommended for fuel systems which flow upwards of 680 LPH. The revised ball-seat valve design is resistant to clogging and offers responsive flow control for stable pressure regulation. Recommended base pressure range is 35-78 PSI. This gen III regulator has a common 1/8" NPT boost / vacuum port (vs. 1/16") which more easily connects to a wide range of common fittings. An o-ring seal has been added under the adjustment screw / washer to reduce vacuum / boost bleed which improves regulator response and tracking error when using small signal hoses. Two -6 AN ORB inlet ports allow for a high volume of pass-through fuel. The secondary port may be plugged for single ended configurations.
We offer an optional 1/8" Male NPT adapters which can be used to replace the vacuum port barb when used with -3 fittings and hose (under add-ons). Please see add-ons to the right of this product listing.
Racetronix offers a range of ORB fittings to configure the inlet and outlet ports to size of your choice. Depending on your flow requirements we recommend -10 AN through -6 AN ORB fittings for the regulator's inlets and -4 AN through -6 AN ORB for the return port.
