I have a 2001 Chevy Blazer LS 2 Door 4x4. I need to replace the fuel lines that have rusted and are leaking. The brake and fuel lines are one big pile of rust along the frame. I cannot find any model specific lines for it. How much different are the ZR2 and 4 door version compared to the 2 door LS? I'm really only interested in the lines along the frame.

 

The 2 door and 4 door lines are not interchangeable. Most auto parts stores have pre-made sections of double flare lines avaliable in different lengths. They are designed for brakes, but can also be used for fuel. The pressure line is 3/8" and the return line is 5/16". Use double flare unions or compression unions to connect the lines. No bleeding necessary, it will happen all by itself when the pump is activated.

 

Ok, I have the fuel lines, that's not an issue. I was hoping the brake lines would at least have parts that would be interchangeable so I wouldn't have to bend them out.

 

Something like this makes bending very easy, and virtually impossible to kink the tube: http://www.harborfreight.com/media/c...mage_18464.jpg
