Just wondering if someone knew this off the top of their head?

 

Think I used 5/16" to run the rear one into the engine compartment. Think I did the same for the front but used one of those brass air line connectors to splice into some existing hose that was still attached to the front. Used fuel injector line clamps in the back. Thinking just regular hose clamps in the front. I Keep records/recipients so could I can go back and look. Will be a bit. Trying to get out the door for work. Will post when I can.

 

I can't remember the size but ran mine up next to the fuel filler neck. cap area.
