Just do like the NHC250s are add a solenoid that will energize the 24v fuel.shut off solenoid and then just add the manual cut all valve for a cable above it. You can have the solenoid energize when the main switch is flipped
Put a p7100 pump on it. Its mechanical. Sorry I don't know what generation 24v your buddy might be getting
If it's cheap it may be worth it. I would just buy an old school bus with a DT466 in it and go that way with the allison 545. If you didn't feel like messing with a stick shift anymore. Then scrap the bus for most of what you paid for it.
