Dear bambu,

Absolutely right about the dealers a) lying to you, don't have a clue.

The fuel filter is part of an integral fuel pump/fuel filter/fuel pressure regulator assembly that is mounted internally in the fuel tank. since you have the LX, I assumed that you have the 3.3 liter engine.

It will be a lot of work to replace the fuel filter, but yes it does exist and can be replaced.

Byron

I thought there are two Fuel Filters. One at the Gas Tank

& one in the Engine. They are not the same.

According to the Hyundai service manual, the fuel filter is integral with the in-tank fuel pump (as Byron said) and is a servicable item.

*The Filter near the Tank only requires Service if the CEL light comes on. Not

a normally serviced item, according to my Hyundai shop. Of course not what

it says here?.

No, there is only ONE fuel filter.

There is the fuel filter in the tank. The fuel tank air filter does NOT filter the fuel, it is related to emmissions requirements. Personally, I won't be replacing (or even inspecting) the fuel tank air filter unless there I have to access that area for some other reason.

I would tend to agree that in-tank filters don't generally need to be replaced (in normal use), however it is listed as a serviceable item, so I will be checking mine at the scheduled interval.

I have checked the service manual again. There is an access panel under the seat - secured by 4 screws. Remove the rear seat squab, remove the access pannel, de-pressurize the fuel system, release the fuel lines, unscrew the fuel pump securing ring, and lift out the fuel pump assembly.

According to my service manual the fuel tank air filter replacement is a requirement at 30K. I just had my 30K maintenance done and the charge for the part and labor was $167. This isn't cheap but it is a warranty issue.

They also tried to talk me into a coolant flush and a tranny flush but I think I will go with the manufacturer's recommendations on these items.

Any thoughts or comments?

This is a picture of the Fuel Tank Air Filter - they gave it to me in a plastic bag when I picked up the car.

Anyone every do this? If so, any tips? Once the fuel pump assembly is out, what do you end up with? Is there a filter that can be removed from the assembly and a new one put in it's place? Pics would be even better!

My dealer said it should be done at 50K. But before I let them in a few months, I'm wanting to know more about the job.

Thanks!

I just got back from my dealer. The 06 Sonata just passed 15k miles and I had them change the oil, rotate tires etc. I changed the air filter earlier in the year.
Strange thing is that I asked about the fuel filter and fuel tank air filter. They told me those are non serviceable items and that their head technician decided not to change them. Ok, so the fuel air filter I may understand.. but the regular fuel filter?
I then called the other two Hyundai dealers in my area and they told me the same thing, no need to change the fuel filter.. I told them it's in the manual but they didn't seem to care.
Are they insane, or is this the norm?

Did the part and labor cost you mentioned include the 30k service or was that solely for the replacement of the Fuel Tank Air Filter?

My cost for 30k was $400 (I learned a hard lesson) or so with the various fluid flushes, but the Fuel Tank Air Filter was not part of it.

Just curious.

Thnx!
