Getting blood from a stone

Well not quite but getting the binder from its bottle at the bottom of the machine all the way to the print head is proving a challenge. I've flushed most of the lines and found a blockage at the input to a filter and now it gets all the way to its little header tank but it shows no sign of going any further. The primer pump is not working, this is a solenoid operated metering pump by Valcor scientific (an SV560) I stripped it down and I think the o-rings are past it. Nothing in my kits will fit nor can be made to fit but looking on the yahoo group reveals a kit from the pump manufacturer is only 33usd, that's OK but it might take a while to come :( boo hoo but a chance to have a clean I guess.
