My 99 Disco 1 keeps eating up fuel pumps. I have changed it out 3 times in the past year and even swapped in a CB pump recently with it failing 2 weeks later. I am starting to wonder what could be causing this to burn out. Could it be a bad wiring harness?
Eating Fuel Pumps

I have never had good luck with aftermarket fuel pumps. I've had quite a few for Range Rovers bad out of the box.
I guess if its running on less than good battery positive voltage it could be bogging and burning up brushes , Check your voltage back there by back probing the wires with a t pin. Get t pins in the sewing section of walmart. box of 100 or so should only cost a few bucks. Then check the voltage drop accross the ground circuit.
I just changed out the fuel filter and got a good used pump from Marty that died before using a full tanks of gas then I put the CB pump in and that didn't last either.
I think that the problem is that used pumps are not really worth a shit and aftermarket pumps are really not worth a shit either.
Discostew mentioned "less than good battery positive voltage". If there is a difference in voltage between the battery, and at the pump, you have resistance somewhere in the circuit that is causing voltage drop. Disconnect the Inertia Switch and and jumper across the wiring. If the voltage reading goes up, the 17 year old Inertia Switch needs to be replaced.
I had to replace the inertia switch on my 1995 Classic SWB, for the same reason when my fuel pump died.

So this just happened. I sprayed the inertia switch plug with contact cleaner and zip ties the plug for a more positive seating and the Disco started right up.
Turned it off and then tried to restart with nothing.

After playing around I ran a wire from the plug bypassing the switch and it started right up. So good chance I am going with a bad switch. I did take the rubber boot off the switch and sprayed it down with contact cleaner.
Bypass the thing all together. Do it with a good crimp n seal connector and don't look back.That switch is a worthless piece of shit idea anyway.
Speaking of fuel pumps-is a buzzing or humming noise (from rear) symptom of failing pump? happened to be out in middle of no-where Colorado yesterday and noticed the (Buzz) (even when in park) so not drivetrain I remember previous(fuel pump) fail made similar noise but was more of a pulsating before it died (in middle of no where Moab) starts and runs fine thinking going to change before it goes
