In the past, when the diaphragm blew out, or rusted through on our accelerator pumps, we had to bite the bullet and buy the entire accelerator because they did not sell the individual diaphragm.
It's about time but we can now buy just the diaphragm for our pumps for about $14 bucks plus shipping.
Before you think you need to replace the diaphragm, you need to make sure that your problem in the accelerator pump is not related to one of the many check vavles this system has.
Because the accelerator pump is only used in the intial take off to build manifold pressure, so your fuel can be sucked into the engine, they sit idle a lot with fuel and oil in them. When fuel starts to break down, it creates a sticky liquid that is prone to gumming up the internal fuel parts. The small springs and balls for these valves are very prone to becoming inoperable do to this. So, before you think you have a problem with your diaphragm, make sure you use a can of carb cleaner, starting at the inlet line to the fuel accelerator pump and spray it through your small line. You can use that small red tube to do this with. This will allow you to see if there is any blockage in one of both of the carbs accelerator injectors or if you might have a problem with one of your "inline" check valves. If you'll notice, just on the outlet side of the pump there is a small round cylinder. This is a check valve.
Because we are just now getting our new parts site "PWCmuscle.com" off the ground, I'm not going to hyper link this part site. They do advertise with us, so it maybe in their ad page in the near future. If you are in need of one before we have it in stock, PM me and I'll send you to the ordering page to pick up that diaphragm...........:cheers:
