fuel line for '86 blazer (Another Newbie Looking for a Part)

[nyreak]

One of my friends who doesn't happen to have much in the way of computer knowledge is looking for a part so I thought I'd help him out. I'll explain the best way I can what he's looking for, and if anyone might have a clue, I'd greatly appreciate it.

He's using parts from an '86 Chevy s-10 Blazer to put together an older Chevy truck (I think it's a '52, but I can't remember for certain at the moment). He needs a fuel line and he's having trouble locating one in this area.

Here is the information that he wrote down for me:
86 Chevy S-10 Blazer Fuel pump connecting hose for electric fuel pump.

He said it's a submersible fuel line, and that's important because other lines are sometimes eaten away by the gas. And he was thinking either 5/16 or 3/8 opening.

Sorry I can't give more information, but anything that needs clarification I can ask him.

Any help would be greatly appreciated!
