For those of you who changed their center section fuel tank from plans toget more capacity, how many sumps did you use, where are they located andhow did you configure the tank bottom to ensure proper water drainage?Wings and tailfeathers painted, just finished painting my numbers on thewing!! now they get hung up and the fuse and engine comes back out. Lordwilling, we'll fly up to Bhead next year...Douwe________________________________________________________________________________

I made one a few months ago. I welded in three fittings. There is one for1/4 NPT on one aft corner for a sump drain. The other side of the tank hasone 3/8 NPT ofr a fuel outlet in the rear corner and one in the frontcorner. I wanted one forward and one aft so I would not run dry eithernose up or nose down. Those two lines will both go down the jury struts andT in the fusalage. The rear one will be configured so there will not be alow point on it before the T and a constant downward path to the gascolatorso water does not collect there with the tail down. I will be able to sumpthe gascolator and the tank drain and that should catch any water in one orthe other side of the tank if the plane is not level.I thought after doing it about an outlet in each corner, but as long as Iremember not to slip in the wrong direction with low fuel it will be O.K.My tank bottom is flat. All the water will go out the aft corner fittingswhen it is on the ground.Brian KrautEngineering Alternatives, Inc.

Hi DouweMy center section is 37" overall. I have 2 tanks holding 8.4 gal eaq. The attached pic shows the 2 sumps, shut off valves and fuel guages. There are also finger strainers in each tank. In addition, I have a header tank in the nose for 2 gal.I was out for 1.9 hours today, 22.5 total on it to this point. Working off the 40 hours for Brodhead and the weather this year is doing it's best not to cooperate. Locals reported a tornado on Sunday just south of the airport but it didn't actually touch down.Dick N.----- Original Message -----
