Fuel Line Size

[RI Chevy Silveradoman]

Does anyone know what size the fuel line is in the photo? I believe the bottom (Larger sized line) is the one that goes to the fuel filter up front. I am trying to install a lift pump and will be cutting the line to insert the pumps. I just need to know what the outside diameter and inside diameter of the line is. Thanks in advance for your help.

Jeff when you cut the lines you can Slip 1/2 in. fuel line(sold at Napa)over the factory lines...try to use a lined hose clamp if you can...

Yep, it is just a standard 1/2" OD hard line. I took a flaring tool and put a small lip on the ends of mine to hold the flexible line onto the hard line and prevent it from slipping off under pressure. Also make sure and use a diesel rated fuel line as regualr gas line can become very hard and brittle in a short time with diesel fuel.
