The HFS-2 offers many top features at a very competitive price. The HFS-2 has PWM valve injection, and the same controller features as the HFS-3. The HSF-2 system starts life as the HFS-3, then the gauge and flow sensor are deleted, and a multifunction dash switch is added. Priced in the same range as other manufacturers Pump Speed Injections systems, the HFS-2 is a giant leap forward in performance at a similar price.
