4.4 Installation of Suction Tube Riser, Suction Tube and Screen For all installations you must use fuel rated pipe sealant on all threaded connections. For new installations cut to size and thread a 2 inch galvanized steel riser for the suction tube and install it into a 2 inch bung at the top of the Liquid Condensate Trap. For all installations install a 2 inch Tee fitting for the Fuel Entry Point on top of the 2 inch gal- vanized steel riser. Measure the length of the suction tube to ensure it can meet the distance requirement in Figure 7. Cut the suction tube to length. When installing the suction tube, ensure the bottom of the suction tube is no more than 1 inch to 1 '/2 inches from the bottom of the Liquid Condensate Trap. Cut a piece of 4 inch by 4 inch piece of screen material, either 18 x 14 aluminum mesh or 18 x 18 stainless steel mesh. Wrap it around the end of the suction tube as shown in Figure 7, leaving approximately 1 inch of screen below the end of the suction tube. Tighten the stainless steel hose clamp around the screen securing it approximately 3/8 inch or more from the bottom of the suction tube. Once the aluminum screen is installed, the suction tube is ready to screw into the bottom of a double-tap bushing. This double tap bushing, with the suction tube, is then installed into the top of the tee fitting. Connect the suction line to the top of the double tap bushing using appropriate fittings (Figures 8 thru 8c) and the other end of the suction line connects to the 140 micron in line filter installed at the turbine syphon port per section 4.1 (Figures 4a and 4b).
