Which one is the Fuel Return Line

I am planning on putting a Fuel Cooler behind my front grill on my Grand Villa. Looking at the fuel tank is see four connectors on the top of the tank. I am guessing that one is for the main fuel line to the engine, one is the fuel line to the generator, one is a vent and the fourth is the return line to the tank from the engine. I am again guessing that the return line it the one closest to the front of the coach. It has a simple brass fitting. Two other have a more sophisticated looking brass hookup and the last one is just a galvanized fitting.

I realize that I could just remove each hose to determine which one is squirting but I don't want the mess and I don't want to get air into the fuel lines. So can anyone help???

Kent,  The easy way is the next tine you drive more than 25 miles, stop, put hand on each hose, the warm one is the return hose, no mess, just clear fact.
Cheers
