Started on the replacement overflow tank tonight. I am losing the plastic oversized OEM, replacing with a top of the line, state-of-the-art aluminum water bottle. Target, $7.99. Yea, ballin'!! Starts with a piece of steel i picked up @ Lowes. Cut it to length & drilled port holes where the mounting screws will go. After its cut, I primed & painted it as well as the hose clamps. I drilled in the bottom of the water bottle 1/2" to fit a general brass fitting. Thread tape & a strong epoxy & its ready to rock. Going to let the clearcoat dry overnight & install it tomorrow. Again, stay tuned....
