Fuel Hoses Lines/piping And Fittings problems of the 1999 GMC Sierra

I was returning from hunting trip ,and when I got off I-75 freeway to go to my home traffic signal ahead was red and pedal went to floor. Fortunately,the light switched to green and I was able to manuever to not collide with car stopped ahead. I nursed it home via back streets at very low speed and to the repair shop the next morning. Mechanic replaced brake line. The fuel line was rusted out at the fuel filter and discovered while other maintainance was being performed. The undercarriage is extremely rusted and I am concerned about pulling my travel trailer due to rusty condition of things. Rocker panels are rusted out as well as rear fender wells. Surely gm can control corrosion better than they are doing. Someone is going to be hurt or killed due to these vehicles rusting so badly.

Gas filter is not working properly, filter is not allowing a lot of gas to flow through because when starting vehicle there is some noise that comes from the engine. Contacted dealer, and dealer was the one who stated that was the problem with vehicle.
