83-94. The 6.9 ran till 87. The only real difference between the 6.9 and 7.3 idi is the bore and head bolt size

What you'd like to look for is a diesel engine with a VE pump (injection pump.) These include older Cummins 4bt/6bt, chevy 6.2/6.5, ford 7.3, vw 1.5d 1.6d 1.9d AND 1996-2003 TDI's (same exact pump as the older diesels, just with a computer), mercedes 240d 300d, and perkins engines found in the older ford rangers to name a few.
Typically these are the engines people choose to run WMO though. Some are direct injection, others are indirect injection (fire into prechambers, and not directly onto the piston.) I've read that the prechambers are better for WMO due to their design, and being able to hold heat better, but it's argued both ways on the boards"
Apparently ve pumps like wmo. The nippondenso rotary fuel pump on a corolla diesel apparently represents a copy of the bosch ve pump, so that helps.
I read online that the best fuel pumps for wmo get their lubrication from the motor oil and not the fuel. Which fuel pumps get lubrication from engine and not the fuel? I heard the merc w123 pumps get lubrication from engine oil, big plus there. I think the corolla diesel fuel pump gets lubrication from fuel.

I read that bosch p pump works best with alt fuels and then the bosch ve pump.
then nippondenso pump on a corolla diesel 1c basically resembles a bosch ve pump.
i thing the w123 240d has a bosch p pump; thinking about going that route.
Reading also that going over 50 % wmo and 50 % diesel blend on single tank setup will cause coking on injectors and smoking exhaust on short trips.
thinking about dual tank setup with a 6 port electronically actuated tank selector valve to start on diesel and turn off wmo.
