Help fur OS 91 Surpass II

[2m86]

Guten Tag.
Ich bin Italienisch, sorry for the english.

I have an OS FS 91 Surpass II with pump.
The diaphragm in the regulator/governor of the pump is deterioreted (enlarged) and dont' work well.
I have tried to contact Graupner (it's the European distributor for OS), 6 e-mail in 2 weeks, never seen an answer.





Where is possible to found this replacement part?
Is the same on the OS 120 Surpass III.


The diaphragm is the part marked with the red arrow.

Grusse
Massimo.

Are you sure the spare part for the pump and the diaphragm are sold separately?

Have a look at the discussion below ?

If you are going to replace the whole pump you can buy it e.g. here :
