Thanks for the post on Gempler's - that looks very much like what I have previously used. I'll probably end up ordering one as the diesel pumps in my area look like they are used about once a week - and who knows what's in the underground tank!!
Dealer installed the pump and it acted up again. They then drained my contamiated fuel and installed fresh, and the BX is running fine. Will have to change suppliers of fuel. They also said it didnt look or act like water, but more of a additive, used by the fuel supplier.
