Mazda lists separate part numbers for the 99/00 and 01/05 so I would prefer one from a BP4W because I don't know what the differences are. Any NB pump inlet from 99-05 should work provided its not from an MSM. I'll probably end up buying like 2-3 of these because I end up buying 2-3 of everything

We've got enough engine carnage on this forum to guarantee one of "you people" has an extra one of these sitting on a broken engine in the garage. I'll give you like, $10 + shipping or something? LMK whachoo got.

 

they're the same, with the possible difference being diameter of the little nipple that feeds the neck from the thermostat housing

 

I figured it was something stupid like that. Got an extra one to sell me?

 

surprisingly, I don't. no idea what we did with em, but if I see a loose one you know its yours

 

Bummer, though let me know if you stumble over one.

As for the rest of "you people" go dig through your parts stash and see what you can find.

I should just start PM'ing everyone who has an EFR, they seem to have a lot of spare engine parts

 

I've got two of them, and I believe one is from an NB. I could probably be persuaded to weld it up for a flipped setup too, if you're so inclined.

 

iv got one. I believe they are all the same as you can cross lower hoses from any year and mazda used one size hose from the back of the head all the way around the motor. Free pick up in SF or San Mateo.
