I need to order a new diaphragm however it looks like I have 3 options to choose from. 31 . .Diaphragm, Acc Pump (Dph#25) AP 5JG-14940-18-00 $26.72 31 . .Diaphragm, Acc Pump (Dph#35) STD 5JG-14940-17-00 $26.72 31 . .Diaphragm, Acc Pump (Dph#45) AP 5JG-14940-16-00 $26.72 Bike is heavily modded. Stock one is done. What are the differences between these 3? Was also thinking about the R&D bowl but i have been out of the game for awhile and don't know if i want to justify that expense until i start racing again. But will go ahead and order it if the consensus is that it should be added. Thanks, P.S don't let the first post fool you. My old account got deleted and had to create a new one.
