2005 Hyundai XG350L Fuel Filter

Hi there, 
If you can get under the car just head to the petrol tank and look for the lines running to and from the tank,
There should be several thin copper looking metal tubes running from the tank to the engine bay,
Generally somehwere along that line should be the fuel canister that should look almost the same as your new one, 
Its then a simple process of unscrewing the old one and screwing in the new one, Be aware not to use any sort of flame light ie lighter when under there as fuel will run out when you remove the old one. If its not under ther then it will be mounted in the engine bayas before just follow those tubes.
You may need to turn the igition on and off a few times once installed to prime the lines if the car does not automatically do this.
If it still wont start try pumping the gas/accelerator once or twice,
Be carefull not to flood the car and you should be away.
Hope this helps
Cheers
Steve
