Ever have to change the fuel filter in the C6?

I would suspect it is because they don't need to be changed all that often. Fuel delivery systems have come a long way. Fuel in general has come a long way towards limiting the types of contaminants that may be introduced to the fuel system. Here is the image from the service manual:
(1) Fuel Fill Hose
(2) Left Fuel Tank Grade Vent Valve
(3) Fuel Feed Pipe to Engine
(4) 5/16 Inch Auxiliary Fuel Feed Pipe
(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:

You can't gain access to the tank by removing a body panel. Even if you could, you can't gain access to the top of the tank to remove the pump and filter assembly as it sits well recessed in the cavity that separates the drivers seat from the rear compartment. You need to drop the rear suspension cradle and then lower the tank to get at it.

since 1996 ALL in ground fuel tanks were MANDATED to be replaced by the EPA. the steel tanks would rust and let fuel into the ground, contaminating the ground water and polluting it.fiberglass fuel storage tanks were installed then and ever since. or they could not sell fuel in the usa. since then, fuel has been very clean. if you have a problem from filters being plugged, better contact your fuel dealer and let him pay for fixing it. contamination is not the problem it once was.

Very Interesting thread. Thank you!. Am looking at the pump replacement thing to budget for labor to see if it is worth to upgrade fuel pump for the new Edel. E-force SC. Watched a clip with Mr. Edelbrock himself claiming the fuel pump replacement is a two day job.

IMO this is an idiotic move by GM.
What if an unsuspecting Corvette owner gets a bad tank of fuel?
You can buy the best fuel for your car, but can't see the condition of it when it's going in or know what the state of the gas stations fuel tanks are in.
So, one bad tank of gas could be 1000's of dollars to fix, versus changing a $10 or $20 dollar in line filter. What....are you going to take the gas station owner to small claims court for the damage and repairs done? How would you prove it?
No amount of rationalization or BS can make me think that this is a good idea.

because with todays fuels and gas stations, if you opened a modern gas pump you would see two big filters that the gas goes through BEFORE it goes in your car, nowadays gas is really clean! as long as you get your gas a GOOD station not some indy station where the owners look like they just got off the boat from the third world, these filters are changed often, inside your tank the fuel pump in surrounded by a VERY fine SS screen there is enuff surface area that you would have to put a bucket of dirt in the tank to clog it, the pump will go out before the screen does and then you can put a new one in

I can't see any significant advantage to the owner by having this system, but GM probably saved about 50 cents per car by having the filter buried in the tank.
This is the kind of penny-pinching that has gottem them such a bad reputation.

Funny to read all the posts about "well, you shouldn't ever have to change it". You shouldnt ever need to replace your windshield either. There's no maintenance interval for that one. However, something tells me thousands of new ones are installed every year.
Anyways, I've got zero pressure at my fuel rail all of a sudden, and the car started up fine and normal last time it was parked in January. Now getting ready to pull it out, and the tank likely has to be dropped.
Just because GM doesn't think it should ever need maintenance, doesn't mean that it can't or won't. Because mine does, and I'm well out of warranty. I imagine I'm not the only guy, either.

I also try to use gas from stations that I know have recently had the old storage tanks pulled out and new ones installed. Ive seen the crap that comes out of those 50 year old steel tanks.

I saw a post of from 2008 about fuel filters. It had a diagram of the fuel system on a Corvette. I'm building a S-10 with a LS motor and fabricating my own fuel cell. I bought a 2007 Z06 fuel pump. I have a question. There is a 5/16 hose barb on the filter housing that goes no where but seems to me would leak off all my fuel pressure unless plugged. In your diagram it looks like it's intended use flowed fuel to the right tank's pump and secondary fuel pressure regulator before returning to the pump in the left tank. Do you think I could just plug it without causing problems? It looks like there is a primary fuel pressure regulator in the left tank pump (that I have). It also looks like it might dump the extra fuel/pressure into the pump canister and not need the returning fuel to function properly. I'm assuming that by plugging that filter hose barb that all will be fine but you seem knowledgeable in this area and would appreciate your input. Thanks, xwnb32d@hotmail.com
