Re: Fuel Pump Options?
I've been running with an L-Jet pump from an '89 Volvo 740 for about 2 years 
. It's the same one used on the L-Jet buses, with a different discharge fitting and electrical connector style...

It works just fine. No issues related to pump delivery. Snag the little "dogbone" fitting piece that goes between the pump and filter in the Volvo application if you use a Volvo pump from the junkyard, cut the nylon tubing off and you have a 7mm right-angle discharge adapter! Also snag the electrical connectors, they are a pair of pin-looking things. The pressure pump (yes, there are TWO on this Volvo) is mounted to a plate along with the fuel filter under the vehicle's midbody. The other pump (low pressure) is in the fuel tank, you DON'T want this one, it won't work as a pressure pump for D-Jet. Be ready to measure the pump's resistance (they're old, and more than likely the one you find will be "open") and get a warranty from the junkyard, at least 50% of the pumps I've pulled have either been "open", or don't produce any pressure when test-run. But if they're OK, they'll run for a long time. As Ray's said before, they seem to start getting noisy first, and give you lots of warning before they die completely. If the one you've pulled is noisy when you run it, get another one.
If you use a new replacement Bus pump, it doesn't appear to need an adapter, looks like it's got a 7mm discharge fitting built-in...

To adapt the tank outlet (7mm) to the pump inlet (10mm), I used the late Bus fuel filter, 133133511, which has one side 7mm, one 10mm...

You will have to make a new wiring harness, but it's quite short, and no problem to make up at all.
