Description
Overview
The FASS Fuel Systems Drop-In Series Dual Electric Heater Probe Kit is an extremely effective cold-weather upgrade for FASS Drop-In Series Fuel Systems being run in freezing climates. Every FASS Drop-In Series Fuel System is engineered with two dedicated ports for electric heater probes, and this kit populates both of them to deliver maximum protection against gelled diesel fuel. If you start and drive your diesel truck or SUV in punishing winter conditions, this is one of the smartest set-it-and-forget-it additions you can make to your fuel system.
Cold diesel is unforgiving. As temperatures plummet, paraffin wax in the fuel begins to crystallize and gel, clogging filters and making cold starts a struggle. This Dual Electric Heater Probe Kit attacks that problem right where it matters most — as fuel enters the FASS System. Both electric heater probes warm the diesel before it reaches the filters, preventing gelling inside the FASS filters and keeping fuel flowing when the mercury drops.
Fully Automatic Operation
With your key in the on position, the Dual Electric Heater Probe Kit automatically activates the moment your fuel temperature drops below 34°F. Once the fuel reaches operating temperature, the probes automatically shut off, so there’s no chance of overheating your diesel fuel and no switches to remember. It simply works in the background, handling whatever Mother Nature throws your way while you focus on driving.
