|BCD is still in the fuel pump business.|
All authenticity concerns aside, internally the early single carburetor Type 3 fuel pumps are slightly different from the early dual carburetor Type 3 fuel pumps, which are in turn very externally different from the late dual carburetor Type 3 fuel pumps. With a quick review, it seems that Italian fuel pump manufacturer BCD is following suit and has made a cost conscious decision to maintain stock on only one part ( part # 1739/6) for the Volkswagen. However, I have to wonder if the fuel pressure delivered is a bit too high for the single carburetor configurations--or, too low for dual carb configurations? I mean, some kind of compromise had to be made in BCD's decision to join the herd of manufacturers who only offer one replacement fuel pump for air cooled VW engines equipped with a generator in their product portfolio. I hope I am wrong, but the pictures and part number in the BCD catalog seem to bear this out. I might email them for more detail, but I'm not too anxious to run down another parts source rabbit hole right now. Worst case, if complete new units are not available, maybe this contact can be used as a spare parts source for the pump diaphragm.
