I've got that engine in my Ambulance RV that I need to sell.
Just make sure you have the Motorcraft Glow Plugs/Beru or they are prone to swell and be difficult to remove.
They loose prime in the return fuel lines from the injectors. They used a metric-sized (10mm?) braided cloth covered hose that doesn't like modern diesel blend. There are also o-rings around each injector for return fuel line that go bad, loose prime.
Easy fix in a weekend, $70ish kit on ebay. I powerwash the engine first, even put a tarp in the cab, removed cowl cover, and blasted from inside. Not much electronics, except glow plug controller i wrapped in tin foil.
attached are the 2 types used (centered or offset), look at yours to determine.
