Is it a decent ideA to try and get a fuel pump from pull and save and is it a difficult job to replace one in a 96 Jeep Cherokee

If you go to the parts counter and say what you're looking for they'll give you a print out of all vehicles with same part and the aisle they're in.

Yes you can get a fuel pump there if they have any similar models but how well does it work is the question.

I don't think they will sell a fuel pump. Best to get a new one.YouTube will have a video on changing a fuel pump in your jeep
