1977 337 G fuel tanks

[Guy Paris]

HI GUY'S,

MY 337 IS IN FOR ANNUAL AND THE CUSHIONING MATERIAL

(LOOKS LIKE CORK) UNDER THE FUEL TANKS APPEARS TO HAVE

MOVED SOME AND MAY BE METAL TO METAL, (BOTTOM OF TANKS

ON THE STRINGER). HAS ANY ONE SEEN THIS AND HAD TO

REPLACE THE CUSHIONING MATERIAL? IF SO WHAT WAS USED OR

IS CESSNA'S PRODUCT THE MATERIAL TO USE OR????

GUY, THE OLD 72 DRIVER...
