Rubber Between Tank & Chassis

Hi all, as I wanted to screw the tank I noticed that the rubber gasket (between tank & upper chassis) on left side is in "bad condition" & should be replaced, anyone knows the part ref or where to find it?
Thx,

Thx, not sure but I think it is : N° 35
T2301953
(PFKL2040580)
INFILL PANEL, FUEL TANK, LH
as it is cheap, I will certainly wait the next maintenance in 05/2020 (the big one) to have it provided & fitted by the dealer. I'll just try to glue the crack at the front end, this crack creates a more bigger gap on right side of the tank. Anyway I won't use the bike before march 2020 when the weather will be dry & sunny….
, so there's no hurry...
