The fuel pump stopped working. No worry. I ordered a new fuel pump repair kit. But then came the surprise, i think my fuel pump is not original. It has only one spring instead of two and the diaphragm (size is the same) is one piece with the push rod. Glass bowl is the same.
Does anybody know what kind of pump this could be?

Thanks from the Netherlands

Chances are is that it is an aftermarket model used to replace the original one. If the stem for the diaphram is not rivited on, you could possibly replace the old diaphram whith the one in your new kit.
