The elevation oftliis tube is readily accomplished by pivoting to the collar 2O a bifurcated leverV 22, the pair of arms 2.3 of whichembrace the outer end of the ytube 'and serve as cams to engage the bottom of the housing for lifting said fill tube when the outer arm portion of Vthe lever is The outer end 24C of each cam arm 23 is more or less flattened so that when the arms 23 are broughtto a verticalposition lever 22 is substantially V'xed and the tube is supported through the arms 23 contacting with the bottom of the housing 18, as indicated in F ig. 2 of the drawings. In this position, also, the outer end of Ytube 11 is brought into close proximity to the top of the housing so that vthe filling nozzle 2l Amay conveniently be inserted therein; and this nozzle, furthermore, servesto obstruct the vreturnof the tube 11 tliiiough'contact with the lever 22.

When the filling operation is concluded and thenozzle 21 withdrawn, lever -22 is turned over to theiposition .indicated in/Fig. 3 of the drawings wherein it lies substantially along the bottom of the housing. Tube 11 is'thereby returned to its normal position wherein its innermost end contacts with the bottom of thetan'k 10; and, in order to prevent unauthorized hlling, provision is made to lock or seal the said lever so that the tube may not be elevated except by an authorized agent. This is conveniently accomplished by providing the louterrend of lever 22 with an opening orV perforation 25 which is adapti ed,`when the lever is in the position indicated in Fig. 3,y to register with a similar perforation 26 of a vlugp27 directed inwardly from the wall of housing 13.

It will be noted in this connection, also, that the position of the 'inner'e'ndof the ll tube remains close to the bottom of vthe tank so that in the iilling operation gasoline is introduced below the level ofthe gasoline therein witli'outtheusual splashing andagitation of thesameand consequent lloss of the more volatile constituents thereof. lWhen thetube is restored to its sealed position, there is, nevertheless, sulficient leakage therethroughsothat the levelV of liquid therein will be the same asthe level of liquid in the tank 10; and asltheupper'en'd of the tube is at all times open and readily accessible, the usual measuring stick maybe inserted to determinethe volume of liquid in the tank.
