Have 2 External WG's seems to be giving me problems, they will not provide any boost even when **** is fully closed. Was told that the diaphram is faulty, but where can I get a replacement? Is there by any chance that I maybe able to repair it myself? What are the causes of this? The diaphram spring? Pls help.

Thanks

Is it possible the boost lines are installed incorrectly? Are the WG's new or used. If you do need a new diaphram I would think the WG manufacturer could provide them for sale.
