Accelerator Pump Gasket

[68Zproject]

I'm having trouble locating a new gasket for the accelerator pump on my dated 4153.  Holley lists a bunch but I don't know if it's 30 cc or 50 originally and Napa has some but I just wondered if it mattered if it was theirs or Holley or whatever.  Mine leaks and I sealed the gasket contacts surfaces so it must be in the diaphragm.

Should be the 30cc. Try to get an original Holley if possible.....Joe

Would suggest getting the Green Diaphragm rather than the black, green more modern fuel alcohol tolerant.

They are all temporary. If you have a Holley sooner or later they leak. Look at cruise in at the stained intakes. Lucky they are cheap and easy to fix.
