Default Holley 4150 accelerator umbrella check valve

I recently noticed I was leaking gas on start up coming from accelerator pump. I took accelerator pump off to replace diaphragm which looked good and replace with new one, only to discover the accelerator umbrella check valve torn apart. How and what parts do I need to fix this 4150 holley,thanks for any help, Bob

It might help to know the model year of the Corvette so this thread can be moved to a more appropriate section.

This section is for Help with the website (account issues, software questions, etc.). Each generation of Corvette has their own section on this website to ask technical questions. Once you provide the year, I will move the thread because this section is not for corvette technical questions.

yes remove the float bowl, put a little oil on the stem and pull it thru the hole. trim off the excess stem so it does not hit the float.

Never ever ever use gasket sealant of any type on any carburetor. Never a good thing
