Fuel pump runs and does not run...

  • Remove the tank sensor from the tank in the trunk and take a look inside the tank with a flashlight. There is probably rust in there, which has ruined the new pump straight away. Before I install a new pump, I first make sure that there is no rust in the entire system. If the tank (which is made of bare steel on the inside and is not coated!) is rusted/smudged, then it is best to replace it. Also inspect the steel pipes and replace if necessary. New steel tank approx. 3-400€, there is a plastic tank from the RSR, but it is worth its weight in gold (2-3000€(!)). And in future always with every tank filling with gasoline with ethanol content (Super95 & SuperPlus98) use fuel stabilizer! At the moment we only know that Aral ultimate 102 is currently produced without the addition of ethanol. Shell v-power again contains a small amount of ethanol and is therefore not ethanol-free!
