Will the fuel pump for a 96 3-door Aspire fit 95 5-door?

It's highly likely, but not guaranteed. While the fuel pumps themselves might be the same, the mounting brackets or other surrounding components in the fuel tank could differ slightly between a 3-door and a 5-door Aspire. The extra doors might not have changed the fuel tank significantly, but it's a possibility.

To be certain, you should:

* Check the part numbers: Find the part number for the fuel pump in your 1995 5-door Aspire and compare it to the part number for the fuel pump in the 1996 3-door Aspire. If the numbers match, they're interchangeable. You can usually find this info on the pump itself or through an online parts database using your vehicle's VIN.

* Consult a parts supplier: Call your local auto parts store (AutoZone, Advance Auto, NAPA, etc.) and give them the year, model, and body style of both vehicles. They can look up the compatibility for you.

Don't rely solely on the year and model being similar; the body style difference is the potential issue. Taking the extra step to verify part numbers or consulting a parts professional will save you potential time and frustration.
