Hey guys,

In the process of replacing my sending unit and steel fuel lines with rubber I found a bad brake line too. It's the line running right from the front of the truck along the driver side frame rail to a flex line over drivers side of rear axel.

Easy question. What size is this line?

Is there any other pointers I should know before I start replacing?

Thanks for everything

should be 5/16"

They look a little smaller.

Could it be 3/16?

On My 1 ton and others, all were 3/16", I'm not sure if theres a diff between 1 and 3/4's, I just saw You have a 3/4....I would figure the same though......but def 3/16" on the 1 tonners.....peace.

Fuel lines are, i would bet the brake lines are also, but to date I have not had to mess with mine.
