How do you put a fuel pump on a Chevy 350 motor?

it depends if the fuel pump is on the motor or in the gas tank if it is on the motor you would have to take the to bolts off the make sure the gastit is all off take hoses off a metal are will come out the motor that is what pumps the fuel make sure the arm is in the same place when you replace it goes on in a certain place when you put back on put gaskiet on and replace bolts hook up hoses and your ready to go if it is in the gas tank you will have to drop the gas tank pull off the metal ring that holds the gas tanks lines in place and it will pull out of the gas tank and the fuel pump will be in there do it the same way you see it and it will work
