I'll go with the restrictor also!

The fact that the header tank overflows AND the wing tank where the fuel
returns too makes me think that the fuel pump restrictor is not in place. Wayne
mentioned it already.
Ask your mechanic about it. The restrictor looks like an ordinary fitting and
might be replaced with another fitting by an ambitious mechanic.

I think there are three fuel problems.
The crossfeed line is being fed from the fuel pump.
The gaskets in the fuel caps are not making contact with enough pressure.
The 1/16" adaptor on the output of the fuel pump is either not installed or
installed on the suction line.
Just a guess!

Subject: [ercoupe-tech] Fuel Tank Problem
Well, decided to take an hour long cross country today in the Ercoupe.
Filled the wing and header tanks as I have always done before. As some will
recall, I just had the engine overhauled, had a carburetor problem when things
were put back together... Did the test flights last Monday and all seemed good
to got outside of the difficulty with the air speed indicator reading high.
Did all the things recommended, have not solved that one... so I am attitude
flying and that is working.
Back to the new problem. Fuel is venting from the right and header cap
continuously during flight. I am using the cork gauge caps that were bought
from Skyport... never a problem before. Aside from the venting through the
front hole in both caps, I am also getting fuel up into the sight glass. The
header tank looks like the fuel is boiling and the right one just fills most of
the sight glass. My A&P said it is not a problem with the new fuel pump as he
put in a spec unit...
Open to ideas until he looks things over on Monday...
Thanks,
John
