(SB-912-063UL free replacement). This is on a 912 ULS and standard XS Cowl & FWF. I used Tygon tube and found what I thought was a route avoiding heat sources etc - turned out not to be, when the tube caught fire after a ground run... this stuff is aviation grade: fuel, acid but not fire-proof! What have others done in their install please? Ideally send photos, or a clear description please. Thanks in advance!

I then run silicone hose between the pump and the tube. On the classic I figure any fuel from a blown diaphragm will stream rearward along the outside of the cowl, hopefully missing the hot bits - that's the theory anyway lol Cheers, Pete On Thu, Jan 16, 2020 at 1:14 PM Paul M 383 wrote: > > How have others routed a drain line from the replacement Corona mechanical > pump?
