I wanted to carry a spare fuel pump in my car, since a fuel pump for a 45 year old car isn't going to be something that is going to be on the shelf in most auto parts stores. I did some research, and found that the pump that is presently listed for my 1963 Chrysler supposedly fits all the way up to about the early 1980's. The pictures of the replacement pump don't look anything like what is presently on the car, so I started doing some digging to learn what the difference is. I learned that the new version will fit, and work on the engine, however, it will require some rearrangement of the plumbing. To me, this is not an acceptable alternative, especially if it fails while I am on the road. I contacted a salvage yard on the Left Coast, and got an original fuel pump for the car. I will be sending it out this week to have it rebuilt with modern parts that will withstand the rigors of the modern gasoline blends that are presently available. I will post additional pictures when it returns. You will note in one of the pictures that there is a pump number stamped on the side of the pump housing. This is the identifying part number. Doesn't matter the brand of pump, it usually is stamped on the pump for identification purposes. If you are driving an old car, it is a lot easier to find it before you need it, then it is after you are broken down on the side of the road, scratching your head wondering what to do next..... Time to break out your wallet and pull out a wad of money to pay the tow truck driver....
