1. A gas tank arrangement for an internal combustion engine, the gas tank arrangement comprising:
a gas tank for containing a combustible gas,
a first fuel pump arranged downstream the gas tank and arranged to increase the pressure level of the combustible gas to a first pressure level, and
a second fuel pump arranged downstream the first fuel pump and arranged to increase the pressure level of the combustible gas to a second pressure level,
wherein the second pressure level is higher than the first pressure level,
wherein the gas tank arrangement further comprises a fuel pump propulsion arrangement connected to the first fuel pump for propulsion thereof, and
wherein the fuel pump propulsion arrangement comprises:
a first side portion arranged in downstream fluid communication with the first fuel pump, and
a second side portion,
wherein a piston is arranged between the first side portion and the second side portion for providing a reciprocating motion there between for propelling the first fuel pump; and
further comprising an additional gas tank is downstream fluid communication with the gas tank;
wherein the additional gas tank is arranged in upstream fluid communication with the fuel pump propulsion arrangement.
