Hoping to find out if I can get a replacement accelerator pump for a quadrajet without buying a kit. I know they sell them separately for the eddys and holleys.
I'll get pics of car up later.
Thanks for looking.

Walker Products Carburetor Accelerator Pump - 64-396​

May not be the exact p/n for your application. There are a couple different Walker numbers, not really sure what the differences are.

Thank you! I'll try to narrow it down when I get the numbers off mine

Here's that number you gave. Says a size 21/32" I'm guessing it's probably the correct one. Maybe someone else will see and confirm.

Here's the style carb and the measurement I got. Seems like a different size?

Similar to a kit, aren't they carb-specific and can be ordered by the number stamped on the carb?

I've been looking on there site and I gather length seems to be the biggest difference.
I found this kit. I like how it has the gasket too because im concerned aboutripping it. (picture) and it skips over my model number 17085212

Just give them a call. I think the longer ones are supposed to provide more volume, but I may be wrong.

The silicone seal is what you need, versus the original rubber seal.
