Fuel Tank Cleaning - Toyota Camry, 2.0L, 1987

After repairing the engine and replacing the filters, I decided to immediately remove and clean the gas tank. To remove it was, to put it mildly, difficult, because I did it alone. The bolts are in an inconvenient place, without a long wrench it will be inconvenient, but as luck would have it, the bolts soured so that they broke off the head on one, WD40 did not help. I have already developed my own method of unscrewing such headless bolts. The method is as follows: punch the rest of the bolt in the center, then drill a hole in it with a smaller diameter so as not to damage the thread on the part. I have a set of asterisk heads. So I hammer in one of these asterisks, a slightly larger diameter of the drilled hole, because it doesn’t become red-hot. Then, slowly unscrew the rest of the bolt with a crank attached to this sprocket. In many cases it helped, unless the bolt is very small.
In general, I removed the tank by this method, having disconnected the filler tube before that, which I had all been beaten with corrosion. On the removed tank, I unscrewed the fuel pump and the fuel level sensor. The mesh on the fuel pump was so dirty that at first I did not realize that it was a mesh that looked like a piece of stone. By the way, I discovered another surprise, I had a pump with a VAZ 2110, that is, from 1.5 to 2 liters, I don’t know if it will be enough for such a volume, until I tested it, but most likely I will have to change it. In the tank itself there is rotten gasoline mixed with water and a shovel of sand. Because of this, the inside of the tank was also beaten by deep corrosion, well that not through and through. Having drained all the remaining gasoline, which was almost brown in color, left the tank for a day so that the remaining gasoline disappeared. Then, putting a plastic brush in there, but not a metal one, can e. began to clean sand and rotten metal from the sides of the tank. Then he took a vacuum cleaner and began to suck it all out with a vacuum cleaner, because it is not so easy to get out through holes in the tank.
I cleaned the filler tube and painted it with regular gray enamel for further protection. I put a new mesh on the pump. When assembling the tank, I missed the cover of the fuel pump and the fuel level sensor with a thin layer of sealant. Well, in general, that's all. There is nothing difficult, you just need to do it together. The entire fuel line is now clean. I filled in several liters of gasoline so that the condensate would not corrode the metal. But gasoline still did not work for me, since there was no working flow meter, so it was not possible to test the fuel pump.
There are no pictures, because it was winter, it was cold and your hands were dirty.
