I have QB wings and  am ready to flush the tanks and the remaider of the fuel system to remove any  trash left behind by the builders. anyone else flush their wings before putting  in the fuel sumps and running the engine? If so with  what?

One way is to install a temporary clear auto type fuel filter in a line going from the firewall fuel fitting to gas cans, or via a temporary hose to the other gas tank.  If you are using an in line fuel filter, like the Airflow Performance one Van’s sells, this should be removed and replaced with a straight piece of tubing so that you don’t trap the trash in it.  You want all the trash to end up in temporary filter.  

   

Fill one tank, sump the tank until you get a clear sample, and then use the boost pump to pump the fuel into gas cans or the other tank via the auto filter.  This way you have clean gas to use over and over until you are satisfied the trash is gone.  If you see any particles while sumping the tanks you are not yet done.  You may want to agitate the gas in the tank by rocking the wing to help dislodge particles and get them to the bottom of the tank.  

   

This is also the time to do a first check to make sure you have minimum fuel flow rate (final check is after you reinstall the permanent inline filter) and calibrate the fuel senders if you are using an electronic engine indication system.

Recommend you use a fluid less volatile than gasoline for the process...like water or stoddard solvent.

I flushed them with water. I also cut an access ports on the rear of the tanks to install the sender units.

  

 I went out and purchased a brand new shop vacuum and blew air into the tanks for a few hours to ensure no water remained. Of course all the opeings were open when i did this to ensure the air being blown in had someplace to exit.
