The next pictures show a finished plumbing installation. In this installation the inlet duct joiner in not

used as it is not needed. If you still want to use the inlet duct joiner you will have to arrange your

tubing and wiring different so it doesn’t affect the installation. Also, you will have to slightly cut

certain areas of the duct joiner to make it still fit, because with the saddle tanks installed it is very

tight.

We anyways recommend leaving the inlet duct joiner out once the saddle tanks are installed, but

we then highly recommend installing a FOD Guard to prevent any dirt to get into the Engine.

Important note: Make sure your tubing to both tanks is exactly the same length, otherwise
they will not fill and empty identical due to different flow restriction.
