gas fuel filter is located in the gas tank as part of the fuel pump --dropping tank ---if diesel located front firewall How to replace fuel filter on HYUNDAI SANTA CM TUTORIAL AUTODOC

assuming that it should have been diesel then clean out the fuel lines and replace the filters and a few litres of petrol in the tank will mix in with the diesel
if it is a petrol and you put in diesel then it is not so critical as the diesel will mix with the petrol and the oil in the diesel will act as upper cylinder lubricant so up to 5 litres left will be ok

The filter module is located under the car, just below the drivers seat.

The first clue is the color of the fluid, the second is location of the spots it is leaving.

The fuel filter is located underneath the car. NOTE: the passenger side is the right side of the car. Underneath the car, at the fuel tank. The fuel filter is located next to the fuel tank, on the right hand side, behind a cover.

The are two locations.The fuel filter is either under the fuse box there are 2 canisters the bigger one is the fuel filter .If not there then it is under the back pasager side wing you have to take the inner protection off.The fuel/diesel filter is under the bonnet, on the left side behind the engine bay fuse box. Adjacent to the 2nd low pressure fuel pump. Thanks.

Black smoke from a diesel engine does not mean you have to change the fuel filter.It is caused by the air filter being dirty.That you need to change.Anyway if you want to change the fuel filter it is located at the front middle of the engine in a black plastic round case with notches around the top.Good luck hope that was helpfull.

a guess... fuel filter should be up against subframe behind rear wheel in front of fuel tank...follow fuel lines down frame rail from motor to back end to find it.... good luck
