6.0 MAGNET INSTALLATION INSTRUCTIONS FOR STEEL TANKS

Assemble the washer on the stud and torque the nuts as follows:

 16-203 kit (4-40 thread) 4-5 IN. LBS.

 16-204 kit (6-32 thread) 7-10 IN. LBS.

 16-205 (disk magnet) should be paired with 16-204 (stud magnet) for polypropylene and aluminum tanks when

the Click Bond stud option is not selected.

IMPORTANT! These edges may be very sharp, which could damage the HydraMat or injure the installer. Apply a

Duct-type tape around the tank opening on sharp edges to prevent damage to the media if:

 the opening is smaller than the width of the HydraMat in its free state or

 the folded/rolled HydraMat must be additionally pressed through the opening

Insert the HydraMat through the tank opening and position on the tank floor. The magnets can be pushed across the floor

with a wooden dowel or plastic tool to make the HydraMat as flat as possible in the desired position for the suction hose

alignment. Be careful not to allow any portion of the HydraMat or suction hose to block or bind the motion of the

fuel level sender float.

7.0 MAGNET INSTALLATION INSTRUCTIONS FOR POLYPROPYLENE OR POLYETHYLENE FUEL TANKS

Position the HydraMat as described above. Locate the disk magnets from kit number 16-205 on the outside surfaces

opposite the internal magnets on the HydraMat. Position the magnets to make the HydraMat as flat as possible on the

tank floor.

8.0 ATTACHMENT OF SUCTION HOSE

Holley recommends the use of a convoluted PTFE hose or a rubber hose designed for use in-tank fuel use. Holley offers

a 2 ft. 3/8” in-tank compatible hose (P/N 26-161). This hose can be attached to the HydraMat before or after insertion into

the fuel tank, depending upon the tank opening size. The torque requirements for all adapters to the HydraMat are as

follows:

 3/8” NPT requires 20-24 FT. LBS.

 1/2” NPT requires 25-30 FT. LBS.

CAUTION! Do not use PTFE pipe tape or sealant paste! Loose particles will be drawn into the fuel pump and it

will fail!

9.0 RETURN HOSE LOCATION

Secure a minimum of 5/16” I.D. return hose so the discharge is directed towards the pickup connection point and

approximately 1” above the HydraMat surface.

10.0 2-TANK APPLICATIONS WITH EXTERNAL FUEL PUMP

Select the largest HydraMat size that can fit through the tank opening. Position an 8AN or 10AN “Y” adapter between the

2 tanks to provide the shortest, equal lengths from the tank flanges. Position the fuel pump as close as possible to the “Y”

and mount it at or below the top surface of the tanks.
