Re: Fuel Tank Sending Unit Removal

["piper_pa20" <piper_pa20@xxxxxxxxxxx>]

Brians, advice is good, but I'd drive the car until I knew the fuel level 
was low and go ahead and drop the tank all the way.  You might want to 
inspect the tank top and maybe clean and paint it while it's down.  I 
usually use a brass punch to unlock the sealing ring. It helps to have a 
water hose standing by if you're working on concrete or some other hard 
surface which can cause a spark.  I'd do it outdoors too for that reason. 
If you spill any gas just flush it away with water like the Fire Dept. 
Safety comes before the environment in my book.

And Pat Whiteside (of the South Bay AMX Club) recently told me that he got 
an NOS tank ring gasket from Chrysler Part #J0941521 Seal O Ring 8059012, 
$3.47.

I'll check with my local Jeep dealer and see if I can order a couple to have 
for spares.

Good Luck,
