Some more progress, the fuel system turned into a larger project than expected as the tank was full of sludge:

I decided to use the fuel tank from the other car, which means it is time to decommission the 83.

While I had the tank and differential out I had to patch up some surface rust spots:

The "audio card" from the 83, something similar may find its way onto the 91 but the music of the engine should be enough for the next year or two:

I ended up using a gas fuel strainer and intake line for the larger size, the only disadvantage to this is the strainer screen size on the gas is much finer than the diesel. This could cause no flow if the fuel gels and might clog up like a prefilter. If this becomes a problem I'll have to swap the screens between the two.

The small nipple on this elbow was filled with solder:

I made a little bracket for the firewall and mounted the regulator in the engine bay:

The single stock gas pump is plumbed through the mechanical pump, but will hold 25psi on it's own:

Once the fuel system was up and running, setup the transmission wiring and shifter:

Used a rod from a w220 or w140, it was just a little long and needed trimmed down and threaded:

The bolts didn't line up, and had to use a washer to hold one of the four in. It would be better to cut out the area and weld in a new plate but this will be fine for now.

Once I buttoned up the rear end, finalized the exhaust and added that lateral support I was talking about earlier:

Time to move up front, there was some more rust damage under the battery tray. I swapped out the sway bar mounts and sandblasted it out. The tray I had already redone in the 83, so swapped over the good parts:

You'll notice coolant lines into the washer tank, that is for heating of the fluid and battery. This is a shot inside, there is a thermostat on the end that controls flow:

For the heater core lines, the exhaust side of the engine I used a line from a 81-85 SD slightly modified, painted is the modified vs the old one from the 83:

This now runs on top of the spring perch:

I also made a steel mount to hold up the intake tube and filter.

Here you can see the short extension around the 603 oil cooler:

Found this perfect little elbow on a X5 CCV system:

Getting closer, just need to finish the throttle cable assembly, wire it all, and fill with juices.
