I am putting my 94 12-Valve 6BT in a 55 Chevy Pick-up (using a 99 Dodge 3/4 Ton frame shortened and narrowed). Can some one provide a circuit diagram for the Fuel Shut-off Circuit. I retained the relays and wiring, just need to know how to tie it into the key switch.

 

 

Thanks - I had found that one a few minutes after I posted. It makes sense assuming the BLK/TAN just goes to ground. Looks like it pulls in with starter relay engagement, and holds in with the key switch on. As for the fuel heater, on with key switch, ckt opens at temp to interrupt the ground.

I'm sure I'll have many more wiring and instrumentation questions as this project progresses.

 

One more semi-related question. The fuel heater in this circuit - that's different that the gtred heater? Where is this "fuel heater" and how do I identify it? Sorry guys, I'm not mechanically retarded (I have a low 8-second quarter mile race car), just new to diesel mods. I had my 94 Ram for 280,000 miles before my son wrecked it - never worked on the engine except the alt, water pump, and starter. Moving the engine to a 55 pick-up so there is nothing there to mate up to the engine.

 

Fuel heater is above the fuel pre-filter, bolted to the side of the mechanical lift pump that supplies the fuel to your Injection pump.

You absolutely don't need it till 0 or below ( usually much below ) and it can be a source of air leaks, so if it were me, and that truck won't go into the frigid north, I would simply remove the fuel heater portion, the pre-filter bowl unscrews, then the heater unscrews, and you can simply replace the pre-filter bowl ( cleaned with a new screen, which from the sounds of it, needs done )

The grid heater is up on the intake manifold, and you really don't need that either. It is built into the intake plate, so you can leave it on, just don't bother wiring it up.

Thanks to all who provided information. Just gettintg up to speed on all of the diesel specifics. I drove my '94 from '96 until my son wrecked it in 2012 and worked on it so little that I never learned a whole lot. Just filter maintenance, water pump, starter, and alternator in about 300,000 miles. And the engine is going to live on in a 55 Chevy pick up on a 99 Dodge frame.
