Hi fellows,
=0A=0A  
=0A=0A
I just discovered=0Athe following problem with my header tank.

=0A=0AIn my =E2=80=93 not=0Aflying yet =E2=80=93 LNC 360 I h= ave since 1 =E2=80=93 2 years about 3-4 gallons of=0Amogas for run-up testi= ng etc.. The headertank is sealed with the standard fuel=0Atank sealer Jeff= co 9700.

= =0A=0A
The Jeffco felt hard=0Aand sticked  to= other surfaces OK. I do not believe that it is a mixing or=0Asurface prepa= ration problem =E2=80=93 even it could.

Now= your opinions /=0Aexperience is asked:
=0A=0A
 
=0A=0A
1.   =    =0AAs it is European mogas with ethan= ol =E2=80=93 could that be the=0Areason ?
=0A=0A
2.      =0A= If it is a prep= aration problem =E2=80=93 why does it stick to=0Aother surfaces =E2=80=93 a= nd the Jeffco should be sealing and the adhesive should=0Anot be influenced= by the gas... ?
=0A=0A
3.   &nbs= p;  =0AIs the Jeffco a bad batch ?
=0A=0A
4= .      =0A= Does one need a fuel tank sealer anyhow in the header tank due=0Ato= the other material (except the upper surface) ?
=0A=0A=
5.      =0A= Any expe= rience with mogas =E2=80=9Ccontaminating=E2=80=9D the glass=0Awith respect = to further proceedings like re-covering again with sealer ? =0A=0A
