I'm fairly sure that no f-body 98+ with LS1 had a return line - they are all regulated by fuel bucket internal regulator.

I'm using the PP Typhoon & TB - no regulator needed...

The regulator in 99+ F-bodies is in the bucket. Any excess pressure/volume is returned back to the bucket via the "T" connector under the car. If you want to run the seperate regulator you will need to pull the regulator out of the bucket. You should be all set without the external regulator.

Only LS1 engines that had the return line were the 97-98 corvettes. The LS1 f-bodies have never had a return.

Try upgrading and installing a new an8 primary and use the existing 3/8 as the return

if you want a return system on the rails... get the 97 vette fuel rails.
