Other Fuel System Hoses Lines/piping, And Fittings problems of the 2002 Chevrolet Suburban

While replacing the rusted brake lines on my Suburban (see tracking number 11066863), I noticed the fuel lines going to the fuel filter were also terribly rusted. It appears the rust emanates from the plastic clamp that secures the fuel line to the frame. The tube nut that goes into the filter appears to be frozen with rust. Salt and dirt are trapped in the plastic clamp and nut, which is impossible to wash out. The fuel lines on top of the fuel tank are likely to be rusted, too.

The rear fuel tank strap broke by the bolt. The strap then pivoted down onto the drive shaft. The only reason the tank did not hit the road is because of the strength of the fuel filler hoses from the gas cap.
