Customer Q&A
Will a mu1613 swap out with a mu1745 fuel pump?

I am not seeing anywhere that these part numbers are connected. Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, model, and specifications match up with our listing, these will definitely fit and function just like the original. Please let us know if you have any other questions.

Why do you have to change the factory pigtail harness , Why didn't they keep the square one don't like the idea of cutting the wire harness ?

Thank you for your question, Tim! If you still have the factory pump on this vehicle, then the plug will be square, not a flat 4-pin plug like this one is equipped with. This is due to a design change made by GM, and all new pumps for these vehicles come with the flat connector. If you already have the flat plug then you can simply reuse it if it is in good condition. They are typically burned out when you go to replace the pump, so they usually have to be replaced anyway.
