Fuel Lines: To rubber or not to rubber

[84cutspreme]

IMO get factory style stainless hard lines and connect with rubber over rear axle, at carburetor feed line and at pump. I am not a fan of AN lines only becuase they are a pain and realistically are rubber anyway. That being said if you spend the money...nylon AN lines and newer teflon lined stuff thats meant to handle crap in our gas or even alcohol/methanol are great choice as well!

Always use a rubber . Another option is OEM nylon fuel line available in the salvage yard or from Dorman. They also make a complete line of fittings

Apparently there is a rumor going around that I prefer stainless braided lines but I am not sure where people are getting that idea.

Are you sure you got them all done in braided lines, I can't tell. Too much shiny.

Great responses here guys! I'm very grateful to you all!

The more I think about this, the more I wonder if it's even necessary to change out the fuel lines.
There is surface rust throughout the undercarriage but nothing horribly cancerous. I don't currently have any leaks in the lines/fittings.
My gas tank was the original problem as it has several pinhole leaks. Everything else is fine.

Is this a necessary thing to do just because the car is 40 years old?

Short answer: yes. Light surface rust is normal. Crusty rust goes deep. It's your call. It may never leak. But if you grabbed a section and tried to bend it and it just broke then you know what to do.
