F3 break Lines

I was thinking of changing all my f3 brake lines and fuel lines to braided lines

I know the truck has 3/16 lines so the conversion for the braided lines is an AN-3

has as anyone ever done this and will I have any issues connecting to the master cylinders ?

I believe the F3 should have 1/4" brake lines and a 5/16" fuel line. I replaced all the lines on my F4, it was not that hard to do.

Are you just changing the existing rubber flex lines or thinking of changing all the hard lines to flexlines? Changing everything to flexlines will give you a spongy brake pedal.

I don't remember from your other posts if this has been brought up before. While you are changing the brake lines you should consider switching to a dual master cylinder.

With the original set-up, if you loose one brake component - wheel cylinder, brake line, etc. - you loose the entire braking system. With the dual MC if you loose one component on one end, you still have brakes on the other. Not great brakes, mind you, but better than nothing.

Something to think about.

Thank you . That is a great suggestion that has not come up Yet I will definitely look into it. I was going to start looking at MC once my disk conversion decision is made. I’ve been getting all my Parts from Rockauto and national Parts Depot. I’ll see if they got something If not. Where would you recommend getting one from ?

I'm sorry for the confusion. I made all new steel lines. I bought new stock flex lines for the front and rear axles from my local auto parts supplier. I did buy my dual master cylinder from Rock Auto. I used stainless flex lines from the MC to the hard lines on the frame. Since all my steel brake lines are 1/4" I used -04 stainless flex lines. You will also need to add proportioning valve and a 2lb residual pressure valve for the front for the disc brakes and a 10lb residual pressure valve for the drum brakes on the rear.
