Blossman Services Inc. designed an autogas LP gas evacuation pump to remove propane from autogas tanks when service or repairs are required. The pump system can evacuate a Gen 3 OEM, fuel pump equipped LPI vehicle tank filled with 44 useable gallons in 1.5 hours to zero PSI tank pressure without venting propane into the atmosphere. The evacuation pump enables a fleet to transfer fuel from a vehicle tank being serviced into another autogas vehicle, a refueling station or a separate LP gas storage tank. The pump is completely air operated, and it comes with rugged pneumatic wheels that allow ease of movement over rough, off-road surfaces. In addition, a visual flow indicator on the pump lets users monitor the transfer of propane during the evacuation process.
