>I just replaced the in tank fuel pump (just the pump motor) and repaired
>a bad low fuel warning switch of the fuel sender in my 84 XN6 sedan.
>To get pump and sender out, access from rear deck (speakers) inside the
>car is required. Pull rear seats, remove deck, peel back insulation and
>you'll see access holes for pump and sender. From the trunk, undo the
>lock rings on pump and sender then remove from inside the car.
>The monting of the new pump motor is with a short length of fuel hose and
>hose clamps. Since the pump motor is not an exact replacement physically
>it does not have mounting holes as the OEM one. So the new pump motor is
>just hanging from the fuel hose to the metal fuel pickup tube. The new
>pump motor have threaded studs for +/- but did not come with hardware. I
>scrounged around and luckily found the right size nuts. Crimped two
>wires to ring spade lugs and soldered other ends to the terminals on the
>pump bracket. Make sure you buzz out +/- and connect them properly. On
>the sedan, negative ground is connected to the pump bracket so there is
>only one wire (+) on the outside of the assembly after you are done.
>Attach pickup screen, reinstall and that's it. Unfortunately the new
>pump is very noisy. I thought maybe it was touching the tank so I raised
>it a few inches but the noise is still there. I bought two of these pump
>motors so I'll have to try the other one next, hopefully it'll be quiet.

>The fuel sender may be taken apart by using a dremel to cut the pushed on
>internal star lock washer on the bottom of the unit. There was a layer
>of crud on the circular contact ring of the low fuel level switch. I
>used 600 grit wet dry paper to remove the crud and the switch is working
>again. Since I destroyed the star washer by cutting it and did not have
>a replacement, I crimped the tube after everything is assembled and
>epoxied it to the phenolic bottom so it won't come apart in the tank.
