Fuel Heater Connector & Pigtail | 2000–2018 Cummins 5.9L/6.7L

Keep your Cummins cold-weather starting reliable with this direct replacement Fuel Heater Connector and Pigtail from XDP. Designed for 2000–2018 Dodge/Ram trucks equipped with the 5.9L or 6.7L Cummins, this connector restores proper electrical connection to your fuel heater — ensuring your diesel fuel stays warm enough to flow freely in cold temperatures.

Why Replace the Fuel Heater Connector?

The fuel heater on your Cummins is critical for cold-weather operation. It prevents diesel fuel from gelling and ensures consistent fuel flow to the injection system when temperatures drop. A cracked, corroded, or broken connector means your fuel heater isn't working — leading to hard starts, rough idle, and potential no-start conditions in cold weather. This pigtail replacement is a fast, low-cost fix that avoids replacing the entire fuel heater assembly.
