24 Valve Stand Alone Wiring out of an FL50

Hello,
I am new to the site. That being said I am looking for some help with stand alone wiring for a 24 Valve. I bought an FL50 cab and chassis and going to transplant this into a 1948 Mack EF. I do have a Blue Chip Diesel FMS system that came with the truck. Any help or suggestions on wiring would be great.
Thanks,
Brent

Welcome! Cool truck! the 24 valve wiring generally isn't too difficult, but is there a reason to avoid using a p-pump?
 
Thanks for welcoming me on board Joe Farmer. No not really, I have the "dead pedal" symptom. So it will need a new / rebuilt pump. If I could find the necessary parts to change it over, would this be the best bet? My father and I bought the truck some years ago and we were going to rebuild the flat head Continental. He passed away and I thought I need to get this Mack on the road. So here I am.
 
I'd the vp is already bad. Then I'd say the p-pump swap is definitely the way to go.

I'd definitely swap to the ppump in that case. The ppump needs very little wiring to function properly. My '48 with a ppump has the shutoff solenoid (3 wires) and alternator voltage regulator (3 wires) wired for the engine to be a weekend driver.
 
Personally, I'd steer clear of P-Pump converting it, since most of the lines manufactured for doing this have a propensity for cracking, leaving you stranded with a one-off part you can't source just anywhere.

Nothing wrong with putting on a new/reman VP44 and giving it a good lift pump, so it doesn't fail.
The Medium duty trucks don't have nearly the ECM failures a Dodge pick up does, either.

Mark.
 
Looks like I need to really do some homework here. I appreciate everyone's thoughts, if you have more please feel free to add. Brent
 
Making a vp stand alone is pretty easy. It's probably even easier with the medium duty ECM. The Dodge only requires power to something like 5 or 6 ECM and pump circuits to get it to fire and run. There's a good youtube video that explains hot wiring it. Search stand alone vp44. Then its just a matter of mounting the throttle pedal assembly. Not a big deal. Or just swap it to a p-pump and forget about the electronics B.S.
 
48 Mack EF Update

Well I took Jeff's advice and went with the 12 Valve. I am gaining on the project. Rear air ride is finished. Working on steering box etc. now.
