I have removed the M103 Engine/Tranny/drive shaft from my 92 300TE and put in the OM603 Engine/tranny/drive shaft from my 87 300D. Use the existing 2.87 Differential for now.

I cut the electrical wiring at the firewall so that the EDS, AFM, EGR Sol, Air Recircl Sol, etc harness are still with the engine.
So far, I have done the following on the electrical
- Convert the 300TE Instrument cluster to Diesel format by just replacing the warning light plastic strip from "check engine" to "Preglow icon" and also removing the "Premium Unleaded" wording from the fuel gauge.
- Wired the 0.75 BK wire from the Preglow timer relay to the instrument cluster "Preglow bulb"
- Replace the 300TE brake booster vacuum line with 300D vacuum line.
- Replace the 300TE key ignition assy with 300D key ignition and connect 2 vacuum lines to the injection pump and brake booster vacuum line.
- Remove the entire windshield/headlight washer hose line from the hood of the 300D and swap to the 300TE
- Rewired the Kickdown switch / solenoid wiring following 300D.
- Disconnect the 300TE CISe electrical harness and swap in the EDS electrical harness. ( carefully labeling the fuse/relay box during swap)
- Remove the O2 sensor, fuel pump assy & harness from the 300te
- Drain out all gasoline from the 300TE gas tank.

Question:
1. Do I have to put a Fuel tank strainer at the bottom of the tank? If I connect a diesel hose from the new fuel tank strainer to the pre filter, the fuel line at the end of the strainer is low and visible from the rear. Any better way?
2. Do I have to flush the fuel tank? I have emptied the gas tank for 4 months now, so remaining gasoline should have evaporated.
3. The 300D comes with 2.65 Differential and the 300TE has 2.87 Differential. Any problem if I keep the 2.87 Diff with the OM603 engine/tranny?
4. The Hall Effect Speed Sensor is connected to the CISe in the 300TE. Where should I connect this in the 300D?

Appreciate any help
