Just starting process of bending the fuel lines for the too, and ive pondered about the wing tank low point drain(non existent on my 15gal wing tank in center back of tank.)
-Ive flipped through the forums, and lotsa dave posts with the diagrams etc, thanks!, pretty cool theres so much info on here,..
but in my situation ive got two 3/8"npt welded bungs at each rear back corner of the upper tank, for fuel feed ,
but zero bung in the center tank baffled area..for sumping water..
-at first i wasnt to concerned, as its feeding all 1/2" al lines, to a scott236401 1/2" fuel selector 3position, upper , main and off, down to a monster c2a type fuel screen/gascolator , then to the full bypass mech engine pump and carb on the jacobs.
I was Thinking the c2a would catch all coming from above , but just curious have any ended up with projects, or built sdtoo's with dual feed upper tanks as per plans but omitted welding bung & drilling through the plywood for a drippy future cca1550/1600 valve?
Thanks in advance.
