Could anyone walk me threw the plumbing for the aux tank under the seat.Does it pump fuel up to a wing tank or does it go to the engine.
This instillation is Experimental so I would like to hear the simplest safest way.
THANKS

Here is a link to Andy's site on a aux tank connection. The parts book shows it plumbed into a plug on the top of the rear strainer. That way it is filtered going up to the right tank. You are not use the right tank for take-off and landing when below 1/3 tank because the rear fitting is not tee'd directly to the shut-off valve like the left tank. Since you are experimental I would definitely use the solenoid valve per the 337. You do not want the right tank to drain back to the Aux tank when not in use. It will overflow and run gas on the ground. This is probably the safest way to plumb the aux tank as it is not in the primary fuel supply to the engine.

I hope this helps.
