My old fuel pump has an electrical port (?) for a square connector. Every new fuel pump I can find doesn't have a square connector; it has an oblong connector.

Do you know how or where I can find the SQUARE style connector fuel pump for the truck listed above 1500 model?

It is the exact same fuel pump on your VIDEO

Hello,

Which engine is in your vehicle?
Is it the 4.3L, 4.8L or 5.3L?
Let me know and I will see what the OEM part number is as that can help determine which one you need.

Let me know of any questions.

Thank you.

Hi Sean, thank you again for your help!

I have attached a pic of the fuel pump I am trying to replace. Every 'replacement' pump on the internet has a different electric port. I need the square 4 pin, while the new ones all show an oblong 4 pin!

Can you help me find the original? Or do I just rewire the square 4 port to a new oblong 3 port?

Thanks again Sean!
