Fuel pump compatibility options?

Do you have a donor vehicle in mind? If so, look up the part numbers for that one and for your model to see if they're the same. I use the Rock Auto web site. I found the pump itself is the same for all engine sizes for '97 and '98 Concordes, but not other car models. This also depends on how you're going to replace the pump. If you replace the entire assembly, the housing is different from year to year. If you take your housing apart and just put a new pump into it, those pumps interchange through multiple years and may be the same for a number of different models. The Dodge Intrepid is the same model but came with different options packages. The fuel pump is the same for a '96 model, and is likely to be the same for other years.

Some options also make reference to fitting only original housings, not aftermarket replacements. Ports and hose routing might be different.

This is what's listed for the pump I researched.
