I’m in the process of replacing my fuel sender and decided to replaced the fuel lines as well.Noticed that my truck has air lines for fuel.Dated 2000.Can I use new air line or is there only a certain type that is multi use?

Not sure...... I've used air line for fuel though, never had a problem.

I would not suggest using air lines for fuel. they will get brittle in short order and crack, flake, and be problematic. I also highly doubt the truck maker used air lines for fuel as well.

Volvo uses a plastic style fuel line, completely different from an air line.

I found it odd when I looked at it and saw that it was an air line and when I saw the date of 2000 and my truck is a 2003 I got to wondering if that’s what Navistar used.Is there a specific type of hose that you suggest?

Freightliner uses plastic lines also. I would think that compression fittings could be used to retrofit a fuel system from rubber to plastic if needed.

The blue Aeroquip SAE100R5 air hose I use is rated for hydraulic fluid, diesel, gas, oil, coolant, etc.
