Have replaced the fuel pump on my K100 with one from a Peugeot 205/309 Gti as the original had been ' got at' by a previous owner. The new pump has an integral aluminium pre filter with no vent pipe connection. Surfing the Forum the indications are that it was fitted to eliminate pump cavitation caused, I assume, by air. What creates these air bubbles, is it under tank temperature, low fuel levels, vibration? Am I going to see this problem in normal day to day running.
The pump change is my starting point at trying to eliminate poor cold starting and erratic tickover, it hasn't! so will look elsewhere. John
