ALT Fuel Relay
WARNING: This page is about a different car, the 2004 Ford Pickup Heritage. However, it is still accessible from the selected car via links, so may be relevant.
The ALT fuel relay is a standard mini-ISO type. The fuel pump relay and ALT fuel relay are controlled by the alternative fuel control module (AFCM). The ALT fuel relay is normally open, while the fuel pump relay is normally closed. When ALT fuel operation is enabled the AFCM will energize both relays. VPWR from the inertia switch is then directed from the fuel pump to the CNG fuel tank and alternative fuel solenoids.
