How hard is it to replace the fuel pump on a 86 Q5000S? Also what is
the difference between the Bosch and Pierburg fuel pumps?

Durangoman,
It's not too hard to do, although it's a far sight better to do when it's
warm outside instead of bitterly cold (when pumps usually fail,
unfortunately).
Step 1: Know that gasoline is flammable/explosive and dangerous to your
health. Always read and follow warnings before picking up tools.
Steps 2 through N:

Apparently some have had success with the Pierburg units, though as shown in
Scott Mockry's site the Pierburg requires some shimming.
Cheers!

I replaced the Bosch with a Pierburg a year ago in my '91 100q. I was not aware
of any shimming. It just popped in and replaced the old one easily.

Run your tank low on fuel b4 replacing because you need to reach to the bottom
of the tank.

The Peirburg is nice and quite. I like it.
