I cant figure out how to edit it. It's different then the Wrangler forum. It's an 03 Trailblazer. I thought there was a section with the year model and basically everything you need to know about the model.

in my original thread I stated my friends TB has a leak in her fuel line. The mechanic told her it would cost 650 dollars. I was wondering if that is about right. My fiancé can fix it and save her that bill. Need the diagram. She said the mechanic said it is the fuel lines above the gas tank. Not sure.

Thanks

I am not sure if this is what you are talking about but the line drawing and fuel lines assembly and parts list can be found here:

Hope it helps!

 

Welcome from Florida. You will have to inspect the fuel lines visually to find the leak. If it is above the tank then you will have to remove the fuel tank and find the spot that is leaking.

 

I can't figure out where the fuel tank is located in this diagram. I'm thinking it's where the circle is?

 

The fuel tank is where lines 21 and 22 connect to the 3 tubes coming out of the circle at the bottom of the diagram. It doesn't really show the tank. That circle with the 3 tubes is the fuel pump.
