2003 Z06 fuel filter question
I have an '03 Z06, manufactured during January 2003. I took the car in for service and asked that the fuel filter be changed, among other things. Once the car was on the lift, I was told that replacing the fuel filter would be around 600 smackers because my fuel filter and pump is one assembly, located inside the gas tank...the gas tank would have to be removed. Has anyone else had a similar experience? Do you just not change the fuel filter? Thanks in advance.

It was recommended to me that I not change the fuel filter assembly until it beocomes clogged, which may never happen. Making the fuel filter and fuel pump as one assembly and putting both inside the gas tank is an egineering marvel, not.

Cruncher, I think you do have the system with the filter inside the fuel tank. To confirm, check the sticker in your glovebox for code "FFS"
Hope this helps

Other than colors available, there are few differences between model years '03 and '04. Partway through model year 2003 (starting with 2003 VIN 35114929 produced on 11/25/02, so I've read), GM totally redesigned the C5 fuel system to accommodate future LEV 2 emission requirements. For 2003 Corvettes only, this system was designated by RPO code FFS, which can be found on the car's Service Parts Identification (RPO) Label. However, the name "FFS" has been unofficially applied to all vehicles with the new system. All 2004s have the redesigned FFS fuel system. You can read more about the redesigned FFS fuel system at the following link:

You can actually see your fuel pump when the car is in the air if you have the older fuel system.
I had my fuel pump/filter changed under warranty cause it wasn't keeping up with my mods, I might've had a dirty filter even though the car only had 12k miles on it. With the new pump and filter I saw an increase about 1 psi on my fuel pressure gauge at idle.
BTW. $600 is actually real cheap. It took the shop about 10 hours to change the pump plus parts. And once you take out the fuel bucket you'd have to replace both the pump and the filter.
