Here is a pic of a fuel tank breather set up. The filler pipe obviously is where you stick the bowser nozzle in & fuel goes to the tank. The rubber hose runs from a secondary pipe ( a nipple if you will) up as close as practical to the outer end of the main pipe. This runs down to a nipple (theres that word again Very Happy ) in the fuel tank. Set up properly this will eliminate blowback provided the main fuel delivery pipe is free of kinks & obstructions. Not standard in early Mustangs but easy to set up. The filler pictured is from an Rx3 sedan. Some welding is required & if you are using a tank that has had fuel in it EVER then a radiator repair place is probably the best place to take your tank to, to carry out any welding. I wont explain what you need to do to safely weld it yourself because if you ozbilt it up, well it wont be pretty. This thread is from a discussion on Ricks "Well Why Not" thread.

Steve,
Is this purely a filling the tank thing, or operation as well?
And is it relevant to just EFI setups, or both?

I only ask as I've read about EFI setups have a beather requirement, but not carb.. And I've not had a problem filling up. (Yet)


Cheers,

This one is just for filling up to stop blowback. For EFI you need a return line from the fuel rail back to the tank as well. Then you can add swirl pots as well depending on your application.

I had heard that if you hook the fuel return line up to your exhaust you get real preedddy flames out your tail pipes...
