Has anyone else ran into their fuel lines on the '95 LT 4dr oxidizing through below the driver's side back door along the frame? Best course of action? any tips or warning are much appreciated!

 

mine did on my 97 in the same exact spot, they started leaking and spittin fuel everywhere and i could smell it everytime i got out after driving, i did a cheap fix on mine by cutting the lines about 2 inches after they went to metal as they came out of the tank and cutting them under the drivers door before they went to the fuel filter and the connector on the return line, and i spliced in rubber fuel injection hose and used fuel injection hose clamps, easy fix for cheap and has yet to give me any problems. just make sure if you do this to use fuel injection hose not just rubber fuel hose because its not rated for the high pressure on these engines

 

Couple of things, same place same deal. I did mine with copper and compression fittings. Its what I had. The prescribed method is steel fuel line and compression fittings.
If I had to do it again I would absolutely use fireman32's method.
Heres the deal cut the steel line on the backside of the filter as far from it as you can so you have plenty to work with. That connection to the fuel filter although it does not look it is specific and costly. I cut mine too close and it was $20. On the backside out of the fuel pump were the rubber hose goes to steel leave plenty of steel. Again I cut mine to close and that was $60. Use a flare tool on the ends and double clamp it.
Again fuel injector hose!

 

Much appreciated! Thanks guys.
