Fuel line size and Brake line size

Hi Guys,

It's 30 degrees outside and snow flurrys, too cold to lay on the ground but not to cold to plan and dream. I want to replace the metal fuel line and all the metal brake lines on my 52 F1. Looking at the JEGS catalog, I can get 5/16" or 3/8" fuel line and 3/16" or 1/4" brakeline, does anyone know the sizes needed for our trucks? I need to pick up a flaring tool and bender as well. Might as well order these as brakes and gas tank are the first things I want to do when the weather improves.

Thanks in advance.

Dennis

Brakes are 3/16" line, fuel is 5/16".

In this case, more is not better. (Don't go bigger. These sizes work fine).

What Randy said.... plus buy some good quality rubber lined line clamps in both sizes.... enough for one every 18" or so.

As for flaring tools/benders... spend a few bucks and buy good stuff. harbor freight junk will just frustrate you... Rigid makes a good flaring tool as does Imperial Eastman.

here's a good thread on benders

https://www.ford-trucks.com/forums/4...rake-line.html

and a link to a page that show how they work...

about flaring tools... make sure you buy 45 deg double flare for common steel lines... but if you're planning on stainless you gotta use 37 degree single flare with the appropriate AN type fittings...

AND don't forget to put your fitting on BEFORE you bend or flare

later,
John

Dennis,

If you don't want the bother of cutting and flaring brake tubing NAPA and most other local auto parts suppliers carry an assortment of brake line tubing in sizes of 6, 8, 12, 20 inches, etc.. up to about 48 inches already flared and with fittings. My truck is not stock but I had no problem running the brake lines using the lengths they had in stock and it was not expensive. I did buy a cheap tubing bender from a swap meet tool supplier and I did not have to buy an expensive flaring tool.

Depending on the fuel needs, you can go 3/8. But brake line needs to stay at 3/16---its all about pressure there and NOT volume.
