my check engine light came on and my friend hooked up his diagnostic machine to it and it read that the problem is "Evaporation". Does that mean it is coming from the fuel tank and has something to do with the new fuel pump?

I have a 2001 Pontiac Sunfire and I just had my fuel pump replaced a few weeks ago?

a fuel system is a closed system,,,sealed ,,,usually a tank,,hose to engine and sometime a return hose to tank,,,,most also have a canaster to collect fumes and return them to tank,,,,some where theres a leak,,,start by looking at gas cap...unless you are a mechanic chaseing down the problem is next to impossible,,

Sounds like an evap system line didn't get hooked back up, or there is a leak.
