Fuel Injection Pressure Sensor Regulator 23280-22010 Replacement for Toyota Lexus Pontiac Scion

This doesn't fit the fuel rail of the 3.5 V6. Sadly its listed or ones the same size on other sites, even major car parts outlets. When you see a price of over $60.00 you'll know you've found the right one for you car. I think this is for a 4 cyl like the Matrix has (maybe). If this is supposed to go in the tank, they need to say it, but I'm pretty sure it doesn't..
