I assume you mean the aux pump located on the left forward fuselage floor. It's shown on the drawings, I don't remember which one right now (at work). However, I believe the new style fuse, which I'm building, has a slightly different configuration than the previous style.
In the meantime, look for two small holes on the forward fuse floor. That's where the pump goes. There are also two small holes on the cabin floor near the fuel selector. That's where the filter goes.
I can take a high quality photo of my drawings and email to you if you don't have them. Assuming of course, that yours is the new-style fuse.
