Ever have to change the fuel filter in the C6?
Do you ever have to change the fuel filter in the C6? Isnt it located in the fuel tanks so how would someone change this without having the dealer do it?

The fuel filter is not considered a maintenance item. It is actually inside the fuel tank and is quite an ordeal to remove it. You should not have to replace it under normal circumstances.

I dont understand why a fuel filter would be placed in the tank and not along the fuel lines where it's easier to get at like other cars.
Guess the dealers just want you bringing it in if it needs changing.

(5) 3/8 Inch Auxiliary Fuel Return Pipe
(6) Right Fuel Tank Grade Vent Valve
(7) Fill Limiter Vent Valve (FLVV)
(8) Secondary Fuel Pressure Regulator
(9) Siphon Jet Pump
(10) Convoluted Crossover Hose
(11) Anti-siphon Hole
(12) Fuel Sender Reservoir
(13) Turbine Fuel Pump
(14) Venturi Pump
(15) Primary Fuel Pressure Regulator
(16) Reverse Flow Check Valve
(17) Fuel Filter
Here is the note on changing the fuel filter:
Fuel Filter
The fuel filter is contained in the fuel sender assembly inside the left fuel tank. The paper filter element of the fuel filter traps particles in the fuel that may damage the fuel injection system. The fuel filter housing is made to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. There is no service interval for fuel filter replacement.

The C5 used a different system which was inline in the fuel feed pipe ahead of the injectors. Not sure what prompted the change. I don't know of many that needed to change the in-line on the C5 and time will tell on what needs to happen on the C6.

This is amazing. There should have been a filter in the line between the tanks and the injectors. I have always made it a point to change the fuel filters in my cars once a year.

GM needs to realize that many Corvette owners need to tinker. Changing a fuel filter once in a while, whether it needs to be changed or not, gives us a great sense of satisfaction, not to mention the performance gains!
My wife's previous car, an Audi A4, leaked every possible fluid. Every couple of days, I had a job to do - get that car roadworthy and keep my wife safe. A few weeks ago I bought her a Cadillac STS. Now I have nothing to do. I feel so useless!

Most GM vehicles are going to this system with the filter in the tank in my experience you will need to change the fuel pump before you need to mess with the filter, I think they are meant to be changed as a unit. Bye good quality fuel and you should not have an issue.

I've had a lot of cars in my life. I cannot think of more than once or twice in my life that I have really had to change fuel filters and that was in old beater '48 and '50 pickups.

Yes you would be. The removal of the tanks is a bit of a challenge. This assembly resides behind the seats:

Is it really necessary to remove one or both of the tanks to change the filter? Looks like a body panel and then go to the top of one of the tanks...based on the illustration.

Fuel filter rode inline near/above the cat mounted on the passenger side frame, there was a heat shield. Changed enough of them to know.
Now, there may have been one in the tank as well, but in almost 500,000 miles (four cars) I never had to change one.
