Oh, and to answer two questions / comments:
- The car I am driving has been in Japan the whole time. It is not uncommon for some foreign cars to be sold with the steering wheel on the "wrong" (i.e. left) side here in Japan. In fact, some people prefer it as a sign of status / exoticism.
- Luckily, I do not have to pay the "shaken". That's another thing you get exempted from with diplomatic plates.

Don't
By way of update: the advice received on this forum was exactly correct! I asked the mechanic to pull the in-tank pump and sure enough, it was toast, which they concur led to the main pump ceasing up. They say they've managed to secure a new main pump and filter, but they seem to be having some trouble locating the appropriate strainer (we're tossing the in-tank pump). In any case, they're checking about the strainer. We are also going to replace the fuel hose that leads from the strainer to the main fuel pump.
I was not informed of the exact part number of the replacement pump. Many on this forum seem to be running the "044" pump. Why the preference for the 044 pump as a replacement? Should I be pushing for this? What will the consequences be if a later pump is fitted with the earlier strainer (assuming we can find one)?
Thanks again!

Found it.
The 044 is a high performance high flow unit. Don't bother going to the expense and aggravation if you're keeping the car in stock or mildly modified form. Best solution I've read here is an in-tank strainer (Lose the pump) and a specific stock pump designed to operate without the in-tank feeder. I'll check and let you know which one it is.
From Greg Brown....."928 608 104 02 gets you the correct pump".
If you do elect to go with an 044, you're going to need to acquire and install the heavy duty wiring kit and Murph's strainer assembly to ensure adequate feed.

should be able to source and expedite the shipping for you if you have issues locally.I have the 044 and Murph's set up in my car now, based on future plans.

The strainer is 928.201.081.04 (through '88), and the pump that was used with that was the 928.608.104.02 mentioned above, and the hose that goes between them is also different, 928.356.550.05 (with a flared end at the strainer).
The later parts are 928.608.013.00 in-tank pump, 928.608.104.03 main pump, and 928.356.550.04 hose.
But I gotta believe that using the newer pump with the strainer would be fine, except perhaps in extreme conditions.
And most in-tank pumps are also just fine, if you replace the short coupling hose.

I once drove the 928 from sea-level 100 degree temps to 8500 feet & cooler temps in one trip. Let it sit and cool, wouldn't fire.
Vented the gas cap, fired right up. Too much suction.
