08 Sonata fuel filter replacement by woodchuck4

The manual calls for fuel filter replacement at 38k. But where is it and how do you change it. Every parts store I called said the filter is NON servicable. What is the scoop here? Does it need to be replaced or not?

It is in the Fuel Tank with the Fuel Pump. Great design!.

I'm waiting to replace it on my 06 model. 38K miles seems crazy low to replace a fuel filter filter. Many car never need a fuel filter replacement. I've got 58K now and all it still fine. Will I ever replace it? Sure, but maybe as part of a large service like when I have tranny fluid changed or something at closer to 80-90K miles.

I asked my service writer about this some time ago, have an 07 with just shy of 40K miles. He said 'we don't bother with that' - it is in the gas tank and apparently accessible by removing the rear seat and a few other things

A fuel filter needs to be replaced from time to time to prevent debris from getting sucked into your engine. Just think about all the dirt particles that are in the underground tank at your gas station. That crud gets sucked into your gas tank when you fill up. If that stuff gets into your engine, it can cause major damage.
 
The fuel filter is very important. However, the time to change it has varied from different cars I have owned. When I was a teenager, I had a '95 Ford Escort which advised changing it every 50k. More recently, I had a '95 Honda Accord which advised changing it every 35k. I'm not sure why there is a large difference in the length of time.
 
Bottom line: you need to change it. When you change it is up to you. Just know that the longer you go, the more of a gamble it is.

I have had Fords with the fuel filter external to the tank (Where it belongs) at 100,000 miles. I would not mind changing the filter every 35,000 miles if it was on the frame rail but in the fuel tank it is costly and could be dangerous. You do not get the tank sealed back-up there could be fuel leakage. Poor design in my opinion.

C'mon man, the symptom of a fuel filter that needs to be changed would be LACK of fuel getting to the engine not "dirt particles getting to the engine". Think about it, a filter that is clogging does not let MORE stuff through.

My 1990 Toyota truck has never had the fuel filter replaced and it runs fine. I think the fuel moves around inside the tank and washes the crud off the filter so the crud stays in the tank.

2004 Sonata engine turns off while driving! by nmc79

Hi! New here! Never had a single issue with my 04 Sonata until this May. The car just shut off while driving - had it towed to a repair shop - they replaced the crank shaft sensor, and the timing belt (which had not broken, but was showing some wear. After getting it back, the car had a rough idle, and ended up shutting off again while driving. Brought it back - they replaced the crank sensor again (said it was faulty) and the ac belt as well. Has had a rough idle since - and is now shutting off again while driving! The weird thing is, if you disconnect the battery for a few minutes, the car will then run again. Also, replaced spark plugs and coils. Going to the dealership Friday, but wondering if anyone else has experienced this?

Is your car a 4 cylinder?
