Fuel Tank Leaks and Repairs
The fuel tank is manufactured from cross-linked polyethylene
which is an incredibly strong material but one which also re-
sists most chemicals, including adhesives. There are no known
adhesives or chemicals that will satisfactorily repair a leak
between am aluminum insert and the polyethylene tank.
Proper preparation of the fittings and careful insertion of the
fuel system components will result in a leak-free installation.
If a leak occurs Sonex Aircraft recommends replacing the
leaking fitting with an Oops Fitting. Do not "slosh" the tank.
Oops Fittings
The Oops Fitting is a replacement / repair for fuel tank fittings
which have been broken lose in the tank. They are available in
two sizes so any fitting in the tank can be replaced:
1/8 NPT, Part Number SNX-G01-20, is used in all locations
excpet the primary fuel outlet where the finger strainer is
installed.
3/8 NPT - Part Number SNX-G01-30, is used only for the
primary fuel outlet.
