I am running Pipe and An fitting and braided line for all of my fuel lines and oil lines. Just would like to know the NPT size for the S4 TII fuel rails and AN sizes you perfer. Its an 88 TII ,with a T70 turbo . I thinking of running a 6AN feed line for the turbo and an 8AN drain. Does that sound sufficient? I am also thinking of using 4AN for all fuel lines. How does this set up sound? Any suggestions? Should i up any of my sizes? I am running a 255 fuel pump with 850's and 720 Injectors. I also have an AEM universal adjustable fuel pressure regulator, i am not running the stock Pulsation damper. I appreciate any input. Thanks Jim

you need to run -8 feed and -6 return with a good fpr man and i think i had a stock rail tapped with either 3/8s or 1/2 ntp before i went to an aftermarket set of rails . run -3 for a oil feed and -10 for an oil return. i ran a -4 and had over oiling issues with that so with calling garret about it they sugested -3 (ie brake line size) and have not had a problem since.

This is for everyone else as well. Feel free to use it but do not consider it 100% gospel for all setups.
