1989 ford f 150 gas tank size?

The gas tank size for a 1989 Ford F-150 varied depending on the specific model and configuration (e.g., regular cab, extended cab, short bed, long bed). There's no single answer. To find the exact capacity for your specific truck, you should:

* Check the owner's manual: This is the most reliable source.

* Look inside the fuel filler door: The gas tank capacity is sometimes printed on a sticker there.

* Check the vehicle's sticker: Often, there's an information sticker located in the driver's side doorjamb or elsewhere within the vehicle listing specifications, including fuel tank capacity.

Without more specific information about your 1989 F-150, I cannot give you a precise gas tank size.
