Since day one, (4 months ago) my PA12 has had a fuel leak from the port tank, when landing, when the tank is relatively full (90%+).
The fuel filler cap has a homemade cork seal, which I've never liked and want to replace with a rubber one and I've kind of suspected the leak is coming from the tank filler, so I've fed from the port tank mainly and landed with it <75% full, which has meant no leaks........
On a test flight today, to re-test the fixed:
Charging system
ASI
CHT
Trim
in addition to the main test item-the new diaphragm in the starboard brake master cylinder (all tests went pretty much perfectly!!) I practiced some slips, left aileron/right rudder went perfectly, as did right aileron/left rudder UNTIL I noticed the stream of blue fluid (fuel) hitting the port perspexes!!!! Clearly fuel leaking from the port tank!!!! The tank was about 60%+ full, but it looked like someone was throwing buckets of fuel at the port windows!!!
Has anyone had a similar experience and was it the tank filler, or something more sinister?!!!
Also, another question please-the fuel selector is VERY stiff to turn, any tips for freeing it up please??
Thanks!!!
