Re: [T3] Fuel pump for EberspŠcher gas heater

<x-flowed>The diaphragm actually hasnt hardened, and the pump is running. I have 
installed it and it runs, but it's not able to pump fuel up from the 
tank. I have looked at a few places online that explain about the 
heaters, I knew most of what was written there already. The heater is a 
B2, btw., so if it just would pump the fuel, it would be ok. I have 
disconnected the fuel hose from the heater (directed into a bottle) but 
the pump isnt moving any fuel, even though it runs.
