Beitrag: [QUOTE="Brandse, post: 1007, member: 1253"] Hello, I guess, the pump would also broken if he doesn´t drove on LPG. The ammount of energy, to heat up a few ltr auf petrol is much more than the pumps use. If we assume that the pump needs 4 amperes and converts everything into heat, dun the heat would not be dissipated through the tank and each pipe, there would be a heating capacity of 12Vx4A=60 watts. You can solder with 60 watts, but you can't overheat several liters of petrol. At 30 degrees, gasoline begins to boil. At 200 degrees, nothing is liquid anymore. All this is not enough to destroy a pump. She certainly had a different problem and would have died the same way if she was running on gas. And today's pumps usually have dry-running protection. Has anyone ever measured a high fuel temperature? With a really melting pump, that would definitely be a fire hazard and soon no longer allowed. So believe me, that's superstition. I believe the pumps burn through. But not because of overheating because they previously overheated the fuel so massively that they would die themselves... Broken Pump: Can be. In cause of driving on petrol (with low gasoline): Never. [/QUOTE]
