I need to replace the airline that runs from the accumulator under the passenger door to the passenger side front airbag. I will replace the fittings at both ends just to be safe.

Can anyone help me with the size/diameter of the line, proper length, and the type/size of the fittings?

No dealer around and I'm a little short on time to research it tonight. Any help is appreciated.

Thanks!
