Does anyone know a good source for a replacement Bosch 1 237 121 881? It has two vacuum inlets. I realize it might not be made any more so a suitable substitute would be welcome too. If nothing else some source that rebuilds them would be welcome. As you can tell anything helps. To anyone who might have one of these, does yours have a pin hole in the front too? Mine does and that doesn't seem right. Thanks in advance folks.
