1972 Chevy Nova Lsx Engine Swap Fuel Return Line
|
Most LS engines have a fuel return line coming out of the intake manifold. Ours didn't. We later learned that '03-and-up 5.3Ls didn't have one. Fortunately we were advised to use a '99-and-newer Corvette fuel filter. These are an inline regulator/filter combination with a return line built in. By doing this, we replaced the filter supplied in the conversion kit and made our install even easier, since we didn't need to run a return line through the length of the chassis.
