I think it has to do with the integrity of the protective shell and
corporate liability. I don't know why one is required. Obviously they
are the same pumps. Do you think it has something to do with mounting
the pump in the engine compartment.? CG Reg? Corrosion issues?. In any
event, my pump is located outside the engine compartment and I see no
reason not to remove the shell.

Why do you think Walbro is lying about this?

You got the same ones as we have,Doug. Yes, you have to bend the
mounting bracket drastically. Pry off the end caps and the clam shell
protection comes apart, exposing the pump. Remove three(?) screws on
the bottom plate to expose the filter.

It appears these do not. Just to remove the mounting bracket
one would have to bend it out of shape quite drastically. I looked
closely at the brass caps top and bottom and it does appear that
they may be able to be pryed off. But in any case the instructions
say the filters are not servicable and there are no spares or
instructions for servicing provided.

Must be a 'new' version as all my Walbro pumps have
accessible/removalbe/cleanable protection screens/strainer wire.

Both my WALBRO pumps came with no replacement filters. A
large box in bold print in the instructions states the following:

" SERVICE DATA
The Walbro Marine Electronic Pump incorporates
two (2) built-in filters, one for filtering fine particles
and the other (a magnet) for trapping metalic
particles. Due to the construction of the protective
outer shell, these filters cannot be serviced."

The plastic outer shell appears to be glued together.
Perhaps this is a newer or different model than the
one you have.

The internal filter on the Walbro can be cleaned. In fact, they
supply
a spare with the pump. Taking the pump apart is a little fussy in
an
emergency situation. I am a little concerned to find out that a
pump
failure may result in a blocked fuel supply due to the wobble
plate.
Right now, I have the Walbro in line with my mechanical pump.

I seem to recall from the WALBRO docs that the pump is not
field servicable. Specifically, it states that the internal
filters
cannot be changed.

Unless you have isolation valves to allow servicing of a
parallel
pump,
series works just as well for backup.
fuel wil flow through the unpowered pump.
