The 20-Amp Relay kit is specifically designed for use with AEM’s High Flow In-Tank Fuel Pumps and other electric fuel pumps and ensures that the pumps perform at their rated flow levels. Both 30 and 20 amp relay fuel pump wiring kits and harnesses have auto-reset style integrated circuit boards that help ensure any electrical shorts are remedied. Each kit includes a pre-wired relay receptacle with 80” of red wire for activation (12 gauge for 20-Amp Relay Kit and 10 gauge for 30-Amp Relay Kit) and 80” of 10 gauge black wire for a high current ground circuit, an Amp relay, circuit breaker with mounting tab, crimp terminals and mounting hardware.
