Reply To: fuel line size

[David Stanton]

The dual fuel lines to the external fuel tank are 1/8 inch I.D., made to withstand the tank pressure.  Sierra #18-8051 is what most of us use.  It is sold in 50 foot rolls, or, some places, like NAPA auto parts stores, sell it by the foot.  NAPA link below.  It is dual hose, although it doesn’t say so.
