Fuel Line

At work and truck is home today, anyone know off hand what size fuel line a 390 engine would utilize (from the tank to the engine)? 3/8 or 5/16?


Thanks in advance!

From: **** hole San Jose ca.
From pump the frame rail hard fuel line is 3/8 and to tank hard line.

Then I've found many trucks with 5/16 gas line pump to carb to be 5/16.
