Per dont worry so much. The diaphram part of the pump needs to be some what plyable for the pump to move. If the gas has made this hard the pump is shot. Second the spark is there because they are breaker points, perfectly natural. These pumps usualy dont work because of the hard diafram and not electrical. And when you do have it running right it will suck the gas up from the tank without being primed. Do you have any reprint of trouble shooting manuals? I trust its a BN2 and not a BN4 like Don is speaking of for his thing. ----- Original Message ----- From: "Per Lindgren" <lindgre@online.no> To: "Type 3 Mailing List" <type3@vwtype3.org> Sent: Thursday, January 02, 2003 4:08 AM Subject: [T3] Fuel pump for Ebersp?cher gas heater > Volks, > > I have a question about an electrical fuel pump for an Ebersp?cher gas > heater.
