This is pretty likely due to insufficient fuel pressure. The fuel pump normally provides plenty, but it can't if it's supply is cut off. I'd suspect dirt in the filter that is above the pump, but if you already replaced that one then you should inspect the brass screen that Mark mentioned. You can look at this somewhat, from above, but you have to remove it from below. If it, and the tank, is dirty, then the cause is almost certainly that the fuel overflow hose that Mark also mentioned is broken. This is a very common problem and results in dirt & water getting thrown into the tank. If you have a pressure gauge that you can connect to the fuel rail on the engine, the best way to diagnose this is to take it for a drive with someone watching that gauge. It should hold at 28-30 psi, but if the pump is having trouble pulling in enough gas you will be able to see the pressure drop as you put load on the engine. Once you fix the problem you will see a fairly constant 28-30 psi. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Too much?
