Cold weather can spell trouble for diesel owners. When temperatures drop, diesel fuel can gel, restricting flow and starving your injection system.

FASS Diesel Fuel Systems helps you fight back with a complete lineup of
Electric Fuel Heater Kits designed to keep your FASS Fuel System running strong in even the harshest winter conditions.


The best part? Our Electric Fuel Heater Kits are a set-it-and-forget-it upgrade! Thanks to thermostatic control, these kits automatically turn on when fuel starts to gel, and automatically shut off when your fuel reaches operating temp.

Why a Fuel Heater Matters

Diesel fuel naturally contains paraffin wax that can solidify in freezing temperatures. Gelled fuel clogs filters and lines, creating hard starts, poor performance, and costly downtime.

A properly installed
FASS Electric Fuel Heater keeps fuel warm and flowing freely, protecting your injection system and ensuring reliable starts.

FASS Electric Heater Kit Options

1. Electric Heater Kit (Standard)

  • Designed for most FASS Titanium Signature Series and Drop-In Series Systems
  • Plugs directly into the filter housing to maintain optimal fuel temperature
  • Simple, clean install with all hardware included

2.  Electric Heater Kit – Dual

  • Ideal for extreme climates or commercial rigs that demand extra heating power
  • Adds a second heating element for maximum cold-weather defense

3.  Electric Heater Kit – High Output

  • Ideal for pickups and semis—can be used as a standalone heater, or in combination with the kits listed above
  • Installs just above the filter, heats fuel as it cycles through the FASS Fuel System

4. Ultimate Electric Fuel Heater Kit

  • Combines all the kits listed above for maximum fuel-thawing power
