what size fuel line/ sending unit

[proud_owner68]

My 69 rt is going to be fitted with a newer model 1977 440 engine since I bought it without any engine.  As of now there is no fuel line in place.  What size fuel line and sending unit woud work best for this setup?  Im not sure if the bigger fuel lines are a must for any era 440.

5/16 to all engines except 440
440 is 3/8 line

That's OK Nacho - we still think you are pretty cool and the chicks won't even notice!
