Sanders went to unvented wing tank caps with his E-Modell already. All later Models have unvented caps. The tanks are still vented but into the header tank, which keeps his vented cap. Using unvented wing caps is solving the spill problem and also should let less humid air into the tanks since the system is breathing now through the header tank cap. Unless somebody altered the fuel system, you should have the unvented caps on there. I would do a test flight in close traffic pattern with the vents plugged and see if there are some adverse effects and if all goes fine, seal the vents for good.

I have vented caps on my Alon and have been told by a number of people that the wing tank caps on this model should be unvented , only the header tank should be vented. I really don't know the correct answer except if I plug the vents on the wing tanks the fuel venting stops. > Bob Bullock > N5621F > 66 Alon A2 > Maryland > ========================================================================== == == > To leave this forum go to: http://ercoupers.com/lists.htm > Search the archives on http://escribe.com/aviation/coupers-tech/ > > > ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
