Genuine Racor 777R Series Fuel Heater/Water Separator:

Racor Part # 777R


The 777R assembly is a complete fuel filtration system that removes contaminants from fuel using the following two stage process:

Stage 1. As fuel enters the assembly, it moves through the centrifuge and spins off large solids and water droplets, which are heavier than fuel, and fall to the bottom of the collection bowl.
Stage 2. Proprietary Aquabloc• II cartridge elements repel water and remove contaminates from fuel down to 2 micron. They are waterproof and effective longer than water absorbing elements.

777R assemblies feature an internal thermostat to protect electric engine controls from overheating by the fuel heater and regulates fuel temperature automatically; warm fuel in the winter, cool fuel in the summer (thermostat setting: on at 40°F (4°C), off at 61°F (16°C). This filter also offers temperature controlled fuel heating with return fuel or engine coolant; thermostat valve open to 95°F (35°C). Other features include a fuel primer port on top of the assembly, a internal check valve that guards against loss of prime, a heavy duty integrated mounting bracket that is part of its one-piece billet machined body, a clear bottom bowl that allows the operator to check for water and solid contamination at a glance, and a self-venting drain. Optional accessories include a vacuum gauge and a water detection system.
