Anyone know how often its recommended ? I know from owning several cars that after time and mileage a mucked up fuel filter will hinder performance. How in detail do we also get access to our fuel filters ?

Actually with the kind of money we're all throwing at our cars we should have one in hardcover. I am really curious on the recommended interval for changing one out. Some of us V owners are raking up those miles ( 30k+ ) and throwing money at injectors and fuel isn't the best if your fuel filter is filled with sh*t

If they don't even list it in the owner's manual, I'm not going to worry about it. It will only cut pressure/flow at WOT anyway, right? It's definitely possible to design the tank, and pump intake, to exclude a lot of the junk that used to clog these up.

More than once I was told by the service dept at the dealer that it's in the tank and you can't really change it.

I'll have to ask my dealer on mon. What is the cost and labor time. If its not expensive i'm interested in getting it replaced and opening up mine after its 30k miles to see what it looks like.

Where did you get this info ? My dealer also said it was in the gas tank and non-replaceable

OK, we need someone with a service manual to confirm.

It should be replaced fairly often - just to be on the safe side. This can create issues that could damage the engine. On average, the premium, higher octane gas does have more contaminants in it than regular gas. If you look at the 2003/2004 Cobra or 1999-2004 Lightning communities, they will speak from experience about religiously changing fuel filters. I changed the filter in my Lightning after each race season. It was fairly easy to get to, was cheap insurance, and kept performance up.

I agree. This was with all my previous performance vehicles. Now we just need to know if our fuel filter is accessible and the part #. I will be the first to do it because I really want to crack open my filter to see what 30k miles have done to it

I have a Helm service manual. It says the filter is in the tank and does not need to be replaced for the life of the vehicle. I have never heard of this before. However, when you get under the car good luck finding an inline filter around the fuel lines.

The earlier V's had an external filter outside the tank in front of he rear passenger wheel. I THINK.....correct me if I'm wrong that the V2s have theirs inside the tank.

That said, I'm lookinig real hard at installing a 10 micron paper replaceable in the lines.

When tickling a Cobras belly (the snake not the Ford), its nice to not have hangnails.

If the manual doesn't even mention it, and GM is covering the warranty, I'm surely not going to think that I know more than them. I guess I'll ignore it and leave it to the pros then......

The filter is a sock around the fuel filter intake :( I'm sure it saves GM about a buck to eliminate the filter but bad design IMO. With everything fuel injected these days I would think dirty fuel would be a huge concern. I'm guessing the bean counters figured it was cheaper this way while paying for any fuel related issues under warranty.

WOW, this thread is pretty old, but here goes. Being a new '09 STS owner, I usually like to change the fuel filter around 75k miles or around 7 years. My engine (4.6) was starting to surge a little on startup. That is why I changed the filter. In fact, the old filter had some restriction compared to the new one. That being said, in days gone by, fuel filter replacement was listed in the Scheduled Maintenance section anywhere from 30k and 100k miles, depending on the manufacturer. The fact that the filter is accessible, just like photorobb said, tells me that it can and should be changed. Fuels are pretty clean today, but not that clean. Fuel injectors really like perfectly clean fuel for best functioning. The service manual clearly states that all Scheduled Maintenance is listed in the Owner's Manual only. True, the fuel filter is never mentioned in the Owner's Manual, and the fuel filter is not listed as a Maintenance Replacement Part. All that said, I am here to tell you that once the fuel filter becomes sufficiently restricted, you will be sitting on the side of the road. Been there, done that with my service van that never needs the fuel filter changed. I purchased a new Mann fuel filter at Rock Auto for $10.00 and then I spent about 1/2 hour changing it. You do need the special tool for the fittings, so if you decide to tackle this job, be certain you have all of the correct tools. Either way, even if you have to pay a garage to change the filter and it costs $100.00 (I do not know the cost), is that not better than having to be towed when you need your vehicle the most? You will still pay the garage, and now the tow charge, to say nothing of the inconvenience- say on a holiday or Sunday?). An OBTW, I disassembled the fuel filter, and I did find traces of water in it. You decide.

IMO, the sock of which you speak is more like a fine strainer to protect the fuel pump. Fine dirt does get through it. Think of it this way- if it was such a good filter, would you want to install it on the pump suction so that when it clogs it will take out the pump as well? The filter on my '09 STS is right in front of the right rear wheel house. This is what the Service Manual indicates as well.
