Thanks for the > suggestions! > > Chip > 85 900 T 16V > 173K miles Glad to hear it got sorted. By the way - if you ever have to change the pump, you don't need to syphon the fuel out first. I did a friends car with him, fuel tank was full, but luckily the parts in the area are plastic - no sparks likely. We removed old pump assembly, found replacement pump only (much cheaper) installed it in the pump assembly and refitted, all with a tank almost full to the brim. Biggest pain was removing the large holding ring - a real pain, and also the pipe unions to the pump - they are a snap fit, but one usually breaks if you are not careful - 1 has a filter inline, and one isn't available separately, which can mean a fiddly job if you happen to break the wrong connector. I also found that removing the rear seat is a real help!
