1968 b -body gas tank
 

Hello fellas, I recently purchased a 1968 GTX with an issue I could use help on. I can't find a diagram on how or where to hook-up . 1) 1 small line on the sending unit next to the main line going to the fuel pump. 2) 2 lines coming out of the gas tank. The car was purchased running as is . I've checked everywhere . If there's any fellow B-body enthusiast I would certainly appreciate any info you can provide.

Thanks
JRR

I think that that line may be a vent line and is just fastened somewhere rather than hooked up to anything.
