Hi, take your time, make sure all the old gasket is cleaned off the carb mount on the manifold, and use a new rubber fuel hose that should come with the new filter. Don't over tighten any nuts and bolts. You will have to crank the engine over for a minute or so while the bowl fills before it will start so don't freak out if it takes some time. after it is running you will have to adjust the idle speed and idle mixture screws, these should be set by you per your Chiltons book about 1 1/2 turns out after lightly bottoming the in. After it is running you will probably have to adjust the high idle on the choke side. Before you close the hood make sure there is no fuel leak. Good luck
