I then fabricated two air filter arrangements:
The Ractive adapter is just a 3" plastic plumbing street
elbow with a PVC joining tube.
The Vanagon air filter box is quite a bit more work to
reshape it and again I use part of a 3" plastic plumbing
street elbow to connect to my MAFM flange.
This is what the Vanagon air filter box top looked like
before I painted it;
The elbow is sealed into the box using epoxy resin and some
filler to fill in the gaps when I got finished reworking the
old vanagon filter top. Looks much better when it is all
Here are pictures of the two installations:
