I recently purchased a 2005 Trailblazer 4.2L 4WD and a few months after, I noticed a hefty fuel leak coming from the fuel connector above the 4WD transfer case. The rigid fuel line going towards the front of the vehicle has rusted through. They do not sell the line to fix it anymore and I was looking for alternative methods and what to use to replace the old lines. Everyone I have talked to is saying that the transmission will have to be dropped in order to replace the fuel lines. I'm thinking of cutting the line before and after the coupling and using a rubber fuel line with hose clamps to do a quick repair of the leak until I can replace the fuel lines. I was wondering if anyone had a fuel delivery diagram for the said vehicle that I can reference to, so I can get my feet wet before I go and replace the lines. Any help would be greatly appreciated as this is my first Chevy that I have owned. I can produce photos and more information if needed. Thank you in advance.
