OK, so this means there is still no consensus on what I should do. I have a situation where I cannot prime my fuel system from a clear plastic bottle with diesel purge fluid in in. The intake hose (the hose to the primary (clear) filter) is in the fluid. Pumping for several minutes does not produce any suction. The primary fuel filter and the hose into the fluid is not clogged.

Any ideas?
