Hello all
I have 2005 Golf and recently had my fuel pump replaced because of a slow fuel leak. This is the fuel pump that is mounted on the side of the PD engine that you can find by following both fuel lines from the fuel filter. I had been using B100 for about 9,000 miles and the dealership told me that biodiesel eats through the soft parts inside of the fuel pump causing leaks. The car still ran fine before I got the pump replaced but I definitely noticed that it seemed to run smoother after the replacement, even with 100% #2 diesel. So my questions are:
1) Has this happened to anyone else? You might not even notice it unless you look at it and see if it is covered with fuel. Mine was dripping down the engine, around the transmission, and leaving a small puddle of black biodiesel smelling liquid on the inside of the bottom cover. There were no drips on my garage floor. It seemed like it probably could have lasted longer but then maybe completely blown out at some point.
2) Is there any way to prevent this and still use greater than B5? Does anybody know of any rebuilds with more resistant materials?
