how do I fix the fuel line on a Mcculloch Chainsaw 3200?

I had to buy a primer bulb, cuz it was rotted out. The new onecame with a blue hose and a longer white hose. Where did I go wrong? I connected the blue hose to the carb nipple under the choke level to the short nipple in the primer bulbe. I connected the longer nipple on the primer button to the top hole in the fuel tank. Then I connected the bigger nipple on the carb to the bottom hole in the fuel tank ...did I do this right. Now..are the holes in the tank supposed to have other nipples in or is the longer hose suppose to go into the tank....???? HELP !!! Gas is leaking
