The AEM diaphragm leaked and pumped fuel through this line because when I removed it, it sprayed pressurized fuel back out. Because of the diaphragm failure it leaked by full fuel pump pressure(E55 pump). My question is: Will the EVAP system eventually take care of all the fuel pumped into the canister, and is this an unsafe situation where I need to take the canister out and drain it?
