ABSTRACT:
A gas priming device combining a resilient bellows in combination with an open cap having an inwardly directed annular flange. The lowermost repeating bellows unit is enclosed and encircled by the inwardly directed annular flange of the cap, so that when the cap is secured to a gas supply conduit, the lowermost repeating bellows unit is squeezed between the upper end surface of the conduit and the inwardly directed annular flange, to form a sealing gasket for the priming device. Priming is effected by covering the hole disposed on the upper end of the bellows and compressing the bellows in the direction of fuel feed.
