i just got a 2001 camaro z28 and im new to the ls1s, i had a 89 camaro with a 377 and i had to get a return style fpr and i am not sure how the new fuel tanks are set up. i have a weiand ls6 intake and i have fast log style fuel rails and i am wondering if i need a return style fpr or not. any help would be great, thanks Ty.

 

The 98 up cars are returnless with respect to the fuel rails.
They have a return, but it is at the rear of the car.

No need to add a retun sysem unless you have big power (700rwhp+) or need to add a boost reference regulator.
