Fuel line sizes?

[barry]

Does anybody know what size fuel lines (both the feed and return sizes)would be used on an '83 3/4 ton with the 6.2. My feed line is rubber from the tank to the engine...not quite factory style
I assume diesel lines are larger than gas lines, am I correct?

No, not always. My 6.9 uses 3/8 feed and 5/16 return, the same as all the V8 Chevies I have had.

I don't know for sure the size of the 6.2, but would bet it is close.
