How do I find and get to the Evap Canister in a 2000 Hyundai Elantra?

the large leak could be a loose tank cap
code p 0441 refers to evaporative emission (EVAP) system--incorrect flow detected === causes ---hose /connection/s,-- intake leak--EVAP canister purge valve
probably need to replace the valve but test first for the large leak or cap loose fault as it may fix both

The fuel filling problem is usually a bad charcoal canister. They get saturated and are not able to breathe properly. ( ruined when people top off there tank) It could be other things maybe a stuck vent valve but that should set a check engine light. As far as the fuse goes, replace it with the correct amperage fuse. If it blows again that circuit will need to be checked for short or over load. (Possible someone added aftermarket device to circuit drawing the circuit over the 20 amps its designed for.)

replace charcoal canister and prob canister close valve as well to be safe.

HAVE VECHICLE SCANNED FOR FAULTY EVAP CANISTER PURGE VALVE IT NOT CONTROLLING EXCESS FUEL VAPORS..THAT WILL CAUSE LOT OF FUEL CONSUMPTION.

P2626. 1. At the Air/Fuel Ratio
P1448: EVAP Canister Vent Control Valve Open
I don't recall a B for any codes, but with this info. it sounds like a vacuum leak at the Canister

Did you use a aftermarket O2 sensor or a genuine Hyundai one? If it's an aftermarket one it may be bad or not as good as the OEM one. See here for more details and other potential causes: P0133

Hello! The 2000 Hyundia line has a common fault in the design of their evaporator system; The handling of fuel fumes. If, at any time, you may have overfilled the gas tank, gas will saturate the charcoal canister. This causes small pieces of charcoal to circulate within the evaporation control system, clogging it up, not allowing the gas tank to be filled. Does your Elantra have trouble accelerating, run rough, or stall? Probably so. Take the car to someone you trust and have them flush the evaporator system with the canister removed. You will more than likely need a new canister.

Large leak?... Fuel Cap not tight or the wrong one is installed. Also, the charcoal canister close valve may be stuck 'open' AND/OR the purge control solenoid valve may be stuck 'closed.'

if you continually overfill the gas tank by trying to top off after the pump clicks off you will get raw fuel into the canister. if that is the case you will need to replace the evap canister and filter.

no fuel should be there only fumes. replace the canister and evap hoses
