The tank comes with Jet Tech O-ring style fuel fitting as standard equipment. The tank comes assembled and pressure tested. No clunks are included.
This Jet Tech Tank is assembled using 3/16" ID fuel fittings and vent. If you need 1/8" ID fittings please tell me in the "Note" box at time of check out or email me.If this tank will be used for gasoline based fuels instead of Jet A or kerosine fuel then you must also order Gasoline Proof in addition to your tank order. This will notify Jet Tech that gasolione proof resin must be substituted.
