Description
Complete dual brushless low-pressure fuel pump with rear siphon assembly with complete wiring harness, controller and a PWM controller (the programming can be adjusted). The second pump engages at a programmed duty cycle so one pump operates during idle and cruising and the other will kick in gradually when programmed too. A billet retainer helps retain fuel in the basket during launches. The assembly installs in the factory tank location.
