Stock Fuel Lines

[Calclips]

What size are the stock fuel lines on an 81 K20 with a 350? I bought an in-bed gas tank and need to know what size lines I should buy (rubber) to run down to the frame and meet up with the stock hard lines down there...


Almost ready to start flogging the hell outta my /forums/images/graemlins/truck.gif...

I don't know where the fuel lines ar located on your truck, but I would run metal line if I were needing more than 12". Metal line is easy to bend and compression fittings are cheap.

Most likely is 5/16" for fuel. Doe's this have return line's?

The truck may or may not have return lines, I have yet to look into that. I don't have the little metal hard-line bender, so I was going to run some rubber fuel line down to the passenger side frame rail and connect it to the existing fuel lines that run there. This setup is temporary for this winter only, I'm gonna go flatbed when I finish my next term at school (October-December).
