Fromwhat I understand you get the filler neck, cap and o ring as a combo, from an s4. I called a local Mazda dealer and she looked up the filler neck and told me its an 80$ part. It's supposed to only be 30$ or so, anybody har the part number from the combo?

 

Go to Mazdatrix.

 

I'm in canada and I want the part as soon as possible.

edit: would the mazdatrix part number be the same or different?

 

Its around 80$ at the canadian dealers. Try to buy used at a junk yard.

 

I drilled and tapped my stock Fd one, total cost less than three dollars

 

Any pics of it?

 

N326-15-17YA list price in the US is $52.83

 

 

I did the same thing just the other day after finding out how expensive it was from Mazda. Awesome!

 

were did you guys get that 1/8" npt nipple? I can only find 1/4"

 

Canadian tire. More or less a hardware store crossed with a Walmart for you Americans. Not sure what your equivalent would be.

 

great idea!

 

You are not looking very hard then.
Old style auto parts stores or the internet.
