The fuel pump on My '66 K-Code Mustang is leaking and I'm looking to replace it. I believe it is the original one. My father bought the car new and probably would have rebuilt it if it ever needed it. It's a Carter button top. I may end up rebuilding this one at some point but replacements seem too cheap to not get one in the meantime. It looks like the Carter M6588 is the direct replacement. Anything I should be aware of?
