I'm sure if explain it all to them they will accommodate and help you
Local parts stores want $500 to $600 gor the fuel pump assembly. I got mine online for under $200. I was going to to the work myself, but it seems to be more detailed work than I had anticipated.
Yes, they will use your parts. I've brought my own parts there since it can be hard to find parts for my car. They try hard to keep the cost down for their customers so they work hard to find the best prices for everything.
