Whats the best way to get to fuelpump to change it
Drop the fuel tank, I hope you don't have anymore than a 1/4 tank of fuel, if you do then you will need to siphon it out. Remove the sender assembly, replace the fuel pump and strainer. Or you can purchase the complete sender assembly, most parts stores will have the part or can get it next day. Also replace the fuel filter and pump relay at the same time so they will honor the warranty
Luckily (?) on a Crown Victoria you don't have to take out the gas tank. Make sure it's empty, disconnect the negative terminal on the battery, disconnect fuel lines, then you tap the lock ring counterclockwise to loosen, then you can pull out the fuel pump assembly. I have the Haynes Repair Manual right here since I have a '93 Crown. :)
That's the difference between books on older rigs, my book shows the fuel tank laying down making access to the sender assembly to remove it almost impossible, then there is the C/V that shows the tank in the upright position but that is the low pressure lift pump design, so for an accurate answer a picture of the fuel tank would really help.
I haven't looked at the bottom of the gas tank in about a year because I have thought that since it's nearly 22 years old, maybe a new fuel pump would be in order. I remember thinking that I'd have to put some jack stands under the frame in the back to have the rear end hang to get more "elbow room" to access the bottom of the gas tank.
