A plastic fuel tank assembly test tool

The utility model discloses a plastic fuel tank assembly test tool comprising a test tool pedestal. A top frame is arranged on the test tool pedestal through a support frame. An oil refill opening detection arm used for detecting a fuel tank oil refill opening position, an air exhaust opening detection arm used for detecting a fuel tank air exhaust opening position and a thermal insulation board support detection arm used for detecting a fuel tank thermal insulation board support position are arranged on the test tool pedestal. The top frame is provided with an oil pump opening detection arm used for detecting an oil pump opening position, an oil filter support detection arm used for detecting an oil filter support position and a shock pad detection support used for detecting positions of fuel tank shock pads. After a to-be-detected fuel tank is placed in the test tool, the detection is realized once test members are closed. The detection efficiency is high; detection can be carried out on positional relation
