The first batch of Highline 4x4 rear mounted fuel tanks are in production! These 40 gallon tanks are internally baffled, take a variety of after market fuel pumps, and bolt between the frame rails of your 73-87 Chevy or GMC pickup. The high clearance 3/16” steel skid plate keeps the tank safe from offroad obstacles and uses factory holes to secure it to the bottom of your trucks frame.

Check out the tank and other great products on our website! https://www.highline4x4.com/
