I am need of some clarification, what year 6.0l came with the regulator in the fuel rail?

I'm not sure about the newest vvt trucks, but I'm pretty sure most of the lq4 and lq9 came with return style fuel systems (with the regulator at the rail)

I know the truck 4.8/5.3's came with return rail until 2003, however the vans are different.

Is everyone by-passing or getting rid of the regulator in the fuel rail and using the vette filter/reg?

No, only if you have a returnless fuel rail. If you have a fuel rail with a return, just hook the feed line to the 3/8 line and run a return, the 5/16 line to the tank. You then can put a $10 fuel filter between the tank and the fuel rail in the feed line, instead of buying a $40 Corvette fuel filter.

mines a 2003 6.0, and it has a return rail. I am using the return system.

ok, I was just curious bc it seems like everyone is running the vette filter/reg.

My '01 6.0L has a regulator on the fuel rail and a return line.
