The A426C pump is a good pump, made with a cast zinc/aluminum alloy body.

There is a revised version now being made with a composite body.

The only reason I mention this is because Ford was having severe corrosion issues with the metal body pumps when exposed to road salt in northern climates. The solution was the composite body.

Does any of this make one pump better than another when the pump is used on a TZE? I rather doubt it.

Rockauto sells the a new composite pump for approx $200usd, so keep that in mind with regards to putting a price on the pump you found.

RobM recently provided comparison details on both pumps, so look up his recent posts if you need more data.
