is a 12 foot mainline to short for an fbody...trans am to be exact....

 

it will depend on where you are putting the solenoids and the bottle.

Our wet kits ship with a 16' line and the dry kits come with 20' as alot of dry kits users are mounting the solenoids under the core support.

 

bottle is mounted in the hatch on the rear deck lid and soleoid is on the right hand side of the lid if your facing it...im assuming it will be to short

 

hey just installed a new 6an main line in my TA. Running from where the right back corner where the spare tire was under the car and up to the noids close to the battey I used 16ft. plus another 2ft that my filter was attached to. So like Ray said 20ft would be great.
