Can you use a 2000 ranger xlt fuel pump to replace the one in your 1999 xlt?

It's highly likely, but not guaranteed, that a 2000 Ranger XLT fuel pump will work in a 1999 Ranger XLT. The fuel systems were very similar between those years. However, there's always a small chance of minor differences in the electrical connector or mounting bracket.

Before purchasing, it's best to:

* Check the part numbers: Compare the fuel pump part numbers from a reputable parts store (like AutoZone, Advance Auto Parts, or NAPA) for both a 1999 and a 2000 Ranger XLT. If the numbers match, you're good to go.

* Visually inspect the pumps (if possible): If you can see both pumps, compare their physical dimensions and connector types to ensure they're compatible.

While the chances of compatibility are high due to the model and year proximity, always verifying the part numbers is the safest bet to avoid unnecessary work and expense.
