You heard right folks, 86-91 (87-91 for TII) N/A and Turbo II all have the same fuel pump! I work at a local auto parts store and I was bored flipping through application books (don't tell the boss) and I stumbled upon the fuel pump application guide (Federal/Carter). For 86-91 all cars had the same part number.

 

Well, your books are wrong.
This doesn't surprise me, as a lot of US OEM replacement do weird things like this.
One look at the FSM will show you two different specs for the fuel pumps.

Haha, it's because the replacements are identical, they don't sell the different pumps at a regular store. (should be about the same as the TII pump, and they just use that one for both n/a and TII)

 

you need to be looking it up where it matters, the mazda parts fische, everything else needs to be taken with a grain of salt

 

 

OEM pieces flow different rates...I'm sure the replacement you're talking about is rated for the turbo.

 

yeah not surprising. however you can come acrost some intersting stuff just fubling around the parts store. a '79 ford crown vic catalytic converter gasket is a near perfect replacement for the one between a RB header& exhaust.

when mail order is the only alternatice, us fc owners got a get creative
