where is the fuel filter located on a 2003 corvette? :banghead:

In the tank. GM now calls it a "Fuel Module" which means they replace everything if something fails. And to complicate matters further there are two fuel systems used on the 2003 cars. The early style is like the 2002 and earlier cars.

The late style is utilized on the 2004 cars.
We don't have any pics on hand of the different versions.

Here is the VIN number break for the early vs late 2003 Vette fuel system:
Build Date: 5th car of Nov. 25 2002
Starting VIN sequence for late fuel system: 114930

Not very fun changing it either, so if you are not big into DIY then I would suggest that you take it to a pro!

Now when replacing these you have to put the same one back in right?

Unless you are doing some serious FI mods... :D

When would you need to change it DTS, rather what power level?
