i just picked up a 91 firebird,v6 5 speed off a guy i work with, the car was put down 3 years ago due to bad brake lines, and a blown fuel line,i ran all new brake lines, wheel cylinders and all that but now i need to know what size are the fuel lines as i need to run new supply and return lines, it would be greatly appreciated if some one could let me know.

 

3/8" and 5/16", respectively.

 

cool thanx for the help
