injection line leaks

I have a 87 300 SDL with 18900 miles. I started to smell fuel the other day and have found a leak at the injector line.
It is spraying out between the line and the compresion nut. The nut seems snug so I do not want to over tighten it.
I backed the nut off and tightened it back down but it still sprays. Is the line bad? If so is there a good site someone could
recommend to but the line and other parts?
Thank you for your time

those nuts

take a lot of torque. with a box combination craftsman with about a 9" handle i basically give it all i have. so dont be afraid of tightening it.

I just had the same thing happen to my 87 TDT the joint where the line flanges is cracked. The more you tighten it if it is like mine the more it will spray. I have to order a new line #4 but do not want to go straight through the dealership.....spendy and not a single parts yard here has one. If anyone knows where to get them I would appreciate it.
