Fuel leak - fuel pump

Hello,

I have the truck over at the stealership trying to track down an oil and fuel leak. They said the fuel leak is coming from the fuel pump and want to charge $700+ to replace it. I have read on here about people commonly having problems with a leaking fuel pump, but tried searching, but couldn't find much. Does anyone have any suggestions or pictures of where it could be leaking from, or what common leaks are associated with the fuel pump area?

They are running a dye test on the oil leak, so no answers on that yet.

Thanks in advance for your help.
