Tandy, John, and the group,
Thanks for the posting of 55-22-02....BUT, I think we are all missing
something here.
Tandy speaks of leaking from the header tank cap..overflowing from the
header tank, when the maximum level is about 2 inches from the top of the
tank...at the level of the return line The return line can be seen ,
carefully looking from the pilots side into the header tank. The pipe is on the
right side of the filler tube, and difficult to see.
This, most likely is due to a restricted overflow line......and/or a
result of the fuel pump being replaced and leaving off the restrictor
fitting. This results in excess fuel being pumped to the header tank , causing
it to overflow, by exceeding the capacity of the return line.
If the return line is not clear, ( and they do get stopped up by varnish in
planes that sit long periods, allowing gasoline vapors to evaporate and leave a
varnish in the fittings, or possible some sloshing compound..). If so,
remove the return line fitting from the rear of the tank, and clean it with a
flexible tool..(.A tobacco pipe cleaner works pretty good). Do not
use compressed air on the header tank to check..it may rupture..., But,
one can carefully blow into the tank (don't inhale), while another is listening
at the wing tanks for bubbles....to insure it is clear.
