My 2003 Sonoma came with a kit like that to change the standard connection over. I'm sure they simply wanted to standardize to something they had on the shelf. I didn't like that idea so I researched my original connection and figured out how to unpin them. I then transferred the old connector to the new pump and avoided any splices. I cannot recall for sure but I think I carefully opened the crimped terminals and re-used them but soldered after crimping.

Do you know what style you have and what style they sent you? Another option, if you want the originals, is likely clipsandfasteners.com or Del City will have original housings, pins and seals.

Daniel,
If the new connector is a heavier duty connector the original harness (vehicle side) could be unpinned and switched to the heavy duty connector using the parts they sent. Then you wouldn't need to splice and you could use the new style on the fuel pump side which came on the new pump.

I can however understand your reluctance to dive into changing the connectors. I've done it before and it's not hard once you learn the trick to unsnapping and unpinning...but it does seem they are all different and some are not obvious. I like the Delphi weatherpacks; simple, they seal well, and pretty obvious assembly but there are likely multiple versions of those now too. Almost every terminal I've seen has a shape like an arrow head so you can push them in but they will not pull out. You simply need to push those fish hook/ arrow head pieces toward the connector. Before doing that though you need to figure out how the plastic body snaps together. I'm not trying to encourage you to try something which you are not comfortable with; simply trying to explain how it's done.

Anyway if you simply cut and splice you need to make certain moisture doesn't get to the connection and second make certain the stiffer/larger portion doesn't end-up in a place where rubbing can occur. There are frequent posts on forums regarding blown FP fuses and at least one recent issue was a short due to a splice on top of the tank. Another listed fuse still blows when FP is unplugged. That more than likely indicates a short to ground in the wire (probably from rubbing or a poorly protected splice).

Submariner,
I tried to explain in my first reply that the pins/terminals themselves need to be changed as well as the connectors to do what I was suggesting. I don't like splices so I took everything apart when I did the job. Understand that sometimes they are difficult to avoid.

I was trying to give Delphi-Packard-Electric credit for the original design of the weatherpack (The multi-cavity with round barrels on the male end). I was thinking of it as an example even though the one I was thinking of was not pictured because I view them as the "mother" of anything I see with the rubber weather proofing in a plastic housing.

Maybe I shouldn't have suggested changing connectors/terminals but it seems like someone able to change a fuel pump would have the level of skill required to change the connectors.
