How much does it cost to build a one-meter-long pit in the fuel tank of the tanker?
It depends on how deep your pit is. If it is shallow, you can find a car shaper for general auto repair, which is actually a large toilet plunger. If it is deep, you may have to drain the oil and then go in and jack it up. If it doesn't work, you may have to cut it off and make it up. Generally, 1. 100 yuan, 2.00 yuan and 3.000 yuan are needed.
