2001 challenger 5699 fuel pump

[396stang]

Hey all, I’m new to the Seadoo scene and could use some help. I just picked up a 2001 Seadoo Challenger. It’s been sitting for 5 years. It has the twin Rotax’s. 770 or 771 I think. I’m not getting fuel to the carburetors. I can back back blow through the lines and it bubbles in the tank so I know the lines are clear. The hoses between the block and pump looks fine on both engines. I’m guessing I’ve got bad fuel pump diaphragms. Where is a good source to buy rebuild kits. I’m sure these carburetors are used on multiple engines and probably multiple makes but I don’t know which ones to search for. I searched the forum and couldn’t find the answer so I’ll just ask.
