Supplies

The following customer supplied items 
are recommended for best results 
when installing a heater:
•  Heater power demand is 8.3 amps 

for 12 vdc and 4.2 amps for 24 
vdc. Due to power demand, we 
recommend our relay kit for the 
safest method of installation. We 
offer several relay kits available 
from your Racor distributor. 

•  Refer to the Heater Relay Kit 

Selection Guide

•  A ON-OFF toggle switch (customer 

supplied) may be used to control 
power to heater relay. This allows 
the operator to cut power to the 
heater relay during summer use or 
servicing procedures. 

•  All wires should be 14 AWG 

(American Wire Gauge) minimum.

•  Threadlocker such as Loctite #242.
•  Motor oil, shop towels, clean fuel 

and torque wrenches.

Installation

This procedure may be done with 
the unit on the vehicle (if space 
permits) or on a work bench. When 
performing procedure on vehicle, 
remove ground cable from battery as 
a safety measure before starting. 

Note: Use a toothpick to remove 
old gaskets that are stuck in the 
sealing gland so the surfaces are not 
scratched. Clean all sealing surfaces 
with a clean, dry cloth.

Refer to Exploded View on page 
4 as you read these instructions 
and install the heater.

1.   Drain all fuel from the Racor by 

opening drain valve (item# 17). 

2.   Remove T-handle (item# 1) and lid 

(item# 3), discarding old T-handle 
O-ring (item# 2) and lid gasket 
(item# 4). 

3.   Remove filter element (item# 5) 

from base/housing (item# 8).

4.   Remove the four (4) bowl ring 

capscrews (item# 19) and pull the 
bowl (item# 15) from the base/
housing (item# 8). You may need 
to tap the side of the bowl (item# 

15) with a rubber mallet to free it. Remove the rubber bowl gasket (item# 
14) and discard. Clean the base (item# 8) gasket gland of any debris with a 
soft shop cloth.

5.   Grasp the turbine centrifuge (item# 13) with a gloved hand and unthread it 

counter-clockwise to remove it. The conical baffle (item# 12) will also come 
off with the centrifuge. An aluminum checkball (item# 11) should be inside 
it along with a light red colored checkball seal (item# 10). 

6.   Notice how the checkball seal (item# 10) is positioned within the base 

(item# 8)—the radiused side faces toward the checkball—see image below. 
Install your new check ball seal at this time in the same orientation so it is 
not forgotten in the re-assembly process. Set these parts to the side, you 
will use them later.

7.   Apply a light coating of motor oil on the o-ring of the 2-wire feed-thru 

(item# 9) and insert connector end thru the base port (next to the fuel inlet 
port). Tighten the feed-thru housing into the base port. Tighten the 5/8” 
feed-thru housing hex (specification: 90 inch pounds). The o-ring will seal 
with just light hand tightening. 

8.   Carefully lower the heater (item# 6) into the filter housing –thermostat end 

first - over the center tube and pull the wires 

through the correct opening 

at bottom of base

 (item# 8). See image below.
