NOTE: We recommend buying a new tank or having your tank professionally cleaned before installation of the
HydraMat.
1. Un-snap the fuel level sender (FLS) float arm from the hanger assembly. Cut off and de-burr the 3/8” supply tube at a
distance of 1-9/16” from the (FLS) bracket edge (Figure 10).

2. Install the Earl’s 3/8” tube adapter into the 16-105 HydraMat outlet and torque to 20-24 FT. LBS. Insert the tube into
the compression sleeve and nut, then position the HydraMat to be in line with the (FLS) bracket. Hand tighten the nut
initially to hold this position and then add another 1/2 to 3/4 turn. (Fig. 2)
