Hi from new braunfels... In late 03 they changed to the C6 fuel system. It just moves the fuel pressure regulator and fuel filter to inside the fuel tank. The fuel tanks themselves also were change as was the location of the fuel pump bucket...
Doesnt really matter unless you are planing to make over 600rwhp. I am currently running out of fuel.. So I am going to do a few upgrades... I was making 530rwhp with a Boost a pump without any fuel pressure drop..
On a side note I'm still using that LM1 wide band you sold me..Thanks
they operate a little different[ffs runs a little higher pressure],ffs has 2 pressure regulators in the tank.ffs' fuel system is all integral,fuel pump/senders are in the top of the tank.the old system has them in the bottom.the design basically is that ffs runs with a lower fuel temp[fuel is cooler] than the old system.it's basically for lowering emissions.ffs is less likely to vapor lock due to the cooler fuel temps.
