Six Pack Center Carb Accelerator Pump Leak

[rr4406pak]

The center six pack carb on my Roadrunner is leaking BAD from the center of the pump lever on the accelerator pump.
Hit hit the throttle and a HUGE jet of gas shoots out of the center of the accelerator pump straight down on the intake manifold. Ahhhhh! Made for a huge puddle of gas on the intake manifold (glad I didn't have a fire!).
Even when not hitting the throttle it is just a constant drip, drip, drip, drip.
I'm assuming that I have a hole in my accelerating pump diaphragm.
Are these easy to change?
Do I need a 30cc accelerating pump diaphragm?
Can someone tell me which would be the right one to order?
Any advice on the fix would be greatly appreciated.
Thank you.

Yes, 30cc. That black would be factory Replacement the green holds up a little better. While you have it off, be sure and check the pump housing for flatness. These almost always warp over time. Any method of flattening is better than nothing ie mill, beltsander, file.

You have to take off the rear carb to take off the center carb. Disconnect the fuel line at the T Brass block. While your at it, it might be a good time to change the float bowl and metering block gaskets since it will be off. Use the green accelerator gasket.

Yes. The rebuilt kit contains it but if you only want to change the pump gasket than yes.
