Fuel Tank Drain
 

Anybody know the size for the drain plug?

I bought a used tank without the plug. And I don't want to have to drag the tank down to NAPA and try differant sizes.

Nobody? Really? I hate it when I stump the experts. :)

I stopped by the Mazda dealership yesterday and ordered one. Should be here in a week or two. Then I can measure for the exact size. If possible, I'd like to replace it with a drain cock.

You know I was under mine over the weekend and saw that plug and thought - hum it seems to me bob asked about that. I wonder what that was?.... Then promptly forgot to go find out!

Here is the correct answer. :)

What I'd really like is a drain port. Once I install the tank and rear cradle, I'll see if I have enough room for this.

Good to know.

Wish I had see this earlier... I have a tank I am scrapping out. I will save the plug just in case....
