Also found this pic of the bus engine before pulling items off…
You sure can tell that it's an International engine. The valve covers, the color of the engine, the CDR tube to the back of the intake. and the throttle cable attachment are all International only items. Also, anyone ever wonder where Ford got the valve cover mounted CDR idea for the Factory Turbo engines? They didn't. If you look at the engine serial number on this engine (a little late now since it's already in the van) you'll see that it starts out "7.3DM2U". That is also an international only thing with the "M" in the serial number.
Have these older photos already on phone not sure if this will give a clue.
You have a fuel heater on the filter head so it's the 7.3 style. There's an o ring to seal the fuel heater. That can leak. You also probably use the two piece fuel filters with the screw on bowl on the bottom of the filter. That can also leak. You can buy one piece fuel filters that go on your filter head and they come with a built in water drain so that eliminates one possible leak point.

I went this route.
The new filter i ordered also has a threaded plug that can be removed and the original water sensor can be screwed into this location if you want to keep your water in fuel light working. Even came with a new oring for the water sensor

Thanks guys
I think I will go the route mentioned..

Went through most of the share your ride thread… lots of nice trucks.

A handful of vans and even less converted to 4x4

IDI engines more of a cult following like the early bronco crowd?

With all the electronics and prices on new vehicles seems like these will be hunted down.

Yes they are. I thinkthere's something special about diesel engines that you can't plug into a scanner.

The prices have really jumped in the last 1 1/2 years or so. That's speaking about around me. Other places may have prices that jumped up sooner.

I made some Progress today. Converter bolts, exhaust, oilfilter and plug. Pulled each injector cleaned, put new copper washers and o rings. Started to make the return lines with the classic diesel Kit. Have the six sections installed.

Here is pics Of Both the “bus” and the Van fuel filter assembly.

The bus is basically a bracket that holds the filter. Nothing to leak?

Thoughts or Comments?
Pro/cons for each?

With the Classic Diesel return kit there are a couple Modifications…

“from the injectors and injection pump return. On most 7.3 fuel systems there will be line coming from the filter header going to the #1 injector return cap, remove the brass barb fitting from the filter head and the bypass ball and spring if not already rotten away and plug the port with the silver ⅛ npt plug included in the kit.”

Like you said, the bus filter head has nothing to leak. That's a pro right there. The filter doesn't have a water separator though. it's the 6.9 style and those used the separate water separator that was known to leak. Do you need it? I don't know. I might remember to drain mine once a year and haven't had water issues yet. If you're at all worried, you can put a filter with a water separator before the electric pump that you're going to install. Maybe International never used a water separator on this fuel filter?

How about the fuel heater? From what I understand that once it starts getting cold gas stations use a slightly blended diesel that prevents gumming up or something like that.
Was the heater used prior to the blended gas? Is the heater needed?

I guess this would simplify the wiring harness. I noticed that the bus harness has even less wiring than the already minimal engine harness…


Thanks…

In speaking with airdog…

My application. Single fuel Tank
Run 1/2”fuel Line from tank to universal pump. 100 gph preset to 8psi

Any size fuel line can be used after the pump. They also said I need to run filter and air separator after the pump.

Seems odd as I thought I would want to catch debri before entering the electronic lift pump.

Glad I called because I would have set the fuel filter up before the pump. (Similar to what was suggested) I would like to see if there is some sort of screen that I can put prior to the pump to catch any large debri.

The reason /the filters will cause a strain on the pump. Therefore need to be placed after the pump.
