Boost Pump Prefilter Connection


Can not connect the boost pump prefilter with fittings provided.

The figure page refers to the pump documentation. Did not receive any. Went to the pump manufacturer ‘s web site. No help.

Appears to be a missing fitting.



Or something else missing..

On a flat surface filter and pump not in-line. Looks like spacers are required under the pump.


Figured it out.

The two blue fittings on the pump are not AN816. No ”AN” marking. AN816 fittings are pipe thread not straight thread.

Remove the AN look alike from the pump. Carefully transfer the “O” ring to the blue fitting on the prefilter. (No idea what the “DT” marking on the blue fitting means). Then everything fits well. All matching straight threads.

I’ll trim the mounting plate so everything lines up.

  • Manual says to leave boot Cowl off till after painting! What is the purpose of this? Maybe for installing windscreen? Can you not just install everything and just mask the windscreen or is there something else you need the Cowl off for? Steve
  • In the S21 progress report # 27 there is talk of an Assembly Alert for using VHB tape to install the lexan to the door frames. However, when I search for the assembly alert -----no joy. My kit did include the VHB tape, but there are no instructions on where to use it. It does not look like there is enough to do the entire perimeter of the door and the center seams, so I am wondering if it is only for the center seam. Or, anywhere the lexan meets the door frame? Guidance please.
  • Hi I am trying to make some room to clean out the boxes and stack the parts. I will need to make a rack. Can anyone tell me the wing skin sizes please the length and width. They will be the largest size so I can then make a multilevel rack to store the bits. I havent got the room at the moment to be able to unpack and store the bits safely so another rack inside the shed will have to be made. I need to get my inventory done asap
