I have 3208 NA´s and will be replacing the supply and return fuel lines.

My current supply hose is 13/32 and can´t read the return size.

Can anyone tell me the recommended hose ID size for CAT 3208 NA's?

Are return and supply typically sized the same?

It's looking like 3/8" or 1/2". Maybe it makes no difference but now is the time for me to find out...

Thanks

I would guess 3/8” ID, that is what I seem to remember Being used on trucks with the NA 3208.
 
Harder to clog a bigger diameter hose.

3/8" should be be fine for both supply and return on a 3208 210.
 
Thanks for all the input.
