Subject: | Fuel Pump Vent/Drain Line Routing |
How have others routed a drain line from the replacement Corona mechanical pump?
(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!

Hi Paul,
Lucky you - yours was free :-)
On my classic cowl, after looking it over and seeing hot stuff everywhere
between the pump and the rear of the cowl, I decided to pop a hole in the
cowl below the pump and redux in a small tube stub, sanded flush with the
exterior. 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

oh, and for the classic owners out there, I also had to take my right side
radiator to a local tig welder and have him angle the inboard outlet away
from the new pump outlets, which were an interference fit against the rad
hose.
cheers

I took a short piece of flex tube, 6mm fuel tube, and then interfaced
with a piece of copper tube, you could use 6mm aluminium, to route past
all the hot bits and then along the radiator ducts to rear.
