Biobor is a "pesticide" of sorts - it kills fungi dead dead dead. It
is best used as a preventative on a routine basis. It is _only_ for
diesel or jet fuel, or other kerosine-like fuels. There are many other
similar diesel fuel treatments to prevent growth in the tanks.
Fungal growth will NOT appear in gasoline.

I was in error in not pointing out earlier that it is a fungal growth,
not a bacterial growth, that causes the problem.

Re: XJ eating fuel pumps
My guess would be a bad ground tag or a bad/dirty ballast resistor if
you have one.
Some have a ceramic ballast resistor on the power side of the circuit to
cut the voltage down to the pump to make the pump sound quieter. The
two wires going to it can just be hooked together to bypass it. On mine
it is way out near the rad on the drivers side fender.
If the pump has a bad ground tag, it can draw too many amps and wear out
fast or only be able to draw enough to jump a bad connection when brand
new.
On some XJ's the main computer ground tags are on the firewall inside
just above the gas pedal, some are on the engine block maybe on the back
passenger side and the main ground is a mesh cable from the engine head
to the firewall.

Re: XJ eating fuel pumps
That was caused from Shell gas wasn't it? It left that black goo inside
the tanks that clogged up the gas senders and filters.
