Brushed pumps do not love 100% duty cycle, and a 525 can pull around 20 to 25 A under heavy load. Running it with PWM cuts brush wear, bearing wear and heat in the tank.\u003c\/p\u003e\u003ch2\u003eFits\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eBMW low pressure fuel pump kits with a ground-trigger controller such as a Motiv Reflex\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eWhat's included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpool wiring harness with braided sleeve\u003c\/li\u003e\n\u003cli\u003e10\/12 AWG Tefzel wire\u003c\/li\u003e\n\u003cli\u003eGenuine Hella solid-state relay\u003c\/li\u003e\n\u003cli\u003eDeutsch connector, plus the mating connector to convert a flying lead to plug and play\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cp\u003eThis harness activates on a ground trigger only.
