Cracked overflow hose, clogged fuel strainer, water in the filter (when the paper filter element gets wet with water gas can't get thru it) or the filter can just be clogged with dirt. If you pull the input line off the pump, the gas should stream out of it in a full, healthy, pencil-sized stream. If it does not, work your way back up that line one link at a time until you find the bottleneck. Or, bad pump relay: these can go bad leading to excessive voltage drop across the relay which leaves less for the pump, this will cause reduced pump output. This is also fairly common. You can check for this by watching the voltage on the relay output. It should stay up close to the system voltage at all times. Alternatively measure the voltage drop across the relay; it should never be more than 1/4 V as long as the relay is energized. If you have the healthy stream and a good relay, yet the pressure drops anyway, clamp off the line feeding to the fuel pressure regulator. If the pressure jumps up as you clamp the line then the pressure regulator is leaking. This is rare, but it happens. All of these things are more likely and less expensive than a new pump. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
