How to fix fuel leak from check valve

Post by startingovercfi » Thu May 16, 2019 1:55 am

Our DA40 with extended fuel tanks has a leak from the check valve in the capillary line (fuel is leaking out the vent under the wing).
Mechanic wants to repair the check valve but can’t get to it/find it.
He sees the standard tanks (in our other DA40) has check valve at end of tank , but for the long range tanks can’t find it or access it.

He thinks he get parts to repair it if he can get access. Does he need to remove wing?
Anyone have insight here?

Help appreciated.
