Fuel Injector problems of the 2000 Chevrolet Silverado

I took my 1500 chev pick-up to a gm dealer in ri,( hurd GMC) after I smelled gasoline when driving, the service dept informed me that the fuel line is rotted (at or near the fuel filter)and leaking gasoline near the exhaust, they told me not to drive the truck, for fear of a fire. They also noted that the brake lines the run down the drivers side frame rail are also rotted . I have repaired other brake lines in the front,last year, because of leaking brake fluid, the gm dealer quoted me a price of around $2000. 00 to replace the entire fuel line from the tank to the injectors. Which included replacment of all rotted brake lines. I have parked the truck for fear of a fire, or possible loss of brakes. The truck is not a rusted mess underneath, I took care not to drive on saltly roads, these lines are made of raw steel, I believe if they were stainless steel, I would not be in this mess. What does one do with a perfectly good truck, but can't drive it for fear of fire or crash ???.

Battery weak, check engine soon light comes on while driving. Replace fuel filter. The vehicle was taken tot he dealer who scanned the pcm and found dtc for engine misfire and injectors not dropping fuel pressure when commanded. Injectors 2 and 6 were cleaned. The cruise control light flashed on and off although the cruise control was not engaged. The dealer was unable to duplicate the problem.

The engine developed a skip while on vacation. I brought it to a garage, the technician diagnosed the problem as clogged fuel injectors. He showed me some clogged injectors from another 2000 Silverado that he had repaired the previous week. He claimed that rust was in the gas tank, and the fuel pump "sandblasted" the rust through the fuel filter and into the fuel injectors. It turns out that my truck had the same problem. He replaced the fuel injectors (all 8) and cleaned the fuel rails. He installed a new fuel filter. This cost over $1,100. After rturning from vacation, I thought I should find the cause of the rust in the fuel system. I took the gas tank out and discovered the plastic gas tank was full of rust. I tipped the el pump assembly upside down, and a great quantity of rusty gasoline poured out. I took this assembly apart and discovered that the fuel pump motor itself (a small steel canister device) was a ball of rust. The pump evidently is not galvanized or plated. The pump motor is the only steel component in the tank. The tank itself cannot rust. The rust from the pump was forced into the fuel system, causing the clogged fuel injectors. The price of the pump, not counting labor, is $409. 00.
