The Universal answer is very carefully especially if you have a type "A"
pump 1931 an older. The are extremely brittle and usually fall apart in your
hands. Every Car is a little different but most cars all you have to do is remove
the 2 flange bolt and disconnect the fuel and vacuum lines.

About 90% of the pumps we do you can't simply install a new diaphragm,
most must be reloaded. In addition some company's will offer a reloaded
diaphragm. Our costumers run into a huge dilemma that when they install
reloaded diaphragms the diaphragm lasts about 20 minutes. This is because in
the earlier days fuel was made of many different components which didn't
hurt rubber like gas does today. We make our diaphragms from a custom made
material that is compatible with the %10 ethanol that is added in the gas
today.

Well the first think you need to check is does your pump have a big gland
nut that contains packing. If it does you must tighten it ever so often to
seal the pump. If you don't have a packing type pump try running the car for
about 5 minutes and see if the leaking stops. The carbon seal needs to
break in to seal perfectly some times.
