Modified pump with a new motor 12v - 21v with a 22 gauge wire that can handle 95 amps. High voltage that can handle high load and heat. The motor is 550RS revolutions per second, smooth Porsche engine. The cost of the motor is 48﷼, with the connection wire for 3﷼. The first pump was purchased for 100﷼ with the gear switch for the motor for 50﷼. Note that the first pump is new, bought from online sites, and is not of the same quality as the modified pump. The motor of the first pump broke down, and I had to modify the pump until it became of high quality and strong suction. Test the goods before you buy. And Allah is the grantor of success.
