Jukebox Ford Engine - Ford expert needed!

[MeatMan]

Maybe I'm being to OCD but I'm mocking up the Revell Jukebox Ford engine and I saw something strange.

As you can see from the pic (sorry about the glare) there is a pulley running from the camshaft area to an unknown piece of equipment.

I've looked at umpteen different engine pics and see nothing on any of them to explain what that might be. And, I've never seen anything but a distributor ever run off the cam.

Something I also noticed, not related is that the instructions call for the distributor to be in the rear engine, when most of us know the Boss 9 distributor is in the rear, like the box shows.

On top of that, the parts list shows a water pump, but the part on the tree with that number is a different set up pulleys, and there's no water pump in the kit but it magically appears on the engine but doesn't show where you would install it. 

Crazy eh! What's surprising, is that there is never any mention of these discrepancies on any of the build narratives I've read.

I'm inclined to leave it off, or run a pulley from the crank and make it a crankcase evac pump.

Any suggestions, or should I just let it go.

Some cars also use it for fuel pump drive as well or external water pump.

Thanks Jesse. That makes sense.

The instructions from the latest re-issue of this kit has the belts wrong, I have the original issue from 1992 and the old instructions calls this belt wich is part 134 out as Water Pump, it's an electric water pump drive and the belt goes from the water pump axle to an electric motor. the water pump itself is molded together with the front engine plate.
We use a similar one from Moroso on the 460 (wich is the same engine family as the Boss 429) in our Super Comp race car and it works well.
The part 133 belt is for the dry sump pump, and there are two more belts that are left over from the other three kits based on this tooling wich were the Charles Carpenter 55 Chevy, the Rob Vandergriff Soff Seal 57 Chevy and the Richard Earle "Christine" 58 Plymouth.

As for the distributor, most Ford engines has them at the front of the engine, the 239-312 Y-block is the exception to the rule and has it's at the rear on them.
The old instruction also has the distributor at the back and that's wrong, this kit shares some parts for the chassis and engine with the other Pro Sportsman kits and it can be a oversight when the instructions were drawn up.

Here is a picture of an electric water pump drive.

Thanks for clearing things up Håkan. So I had it backwards, the belt drives a standard style water pump from the electric motor.

Yes.
The Meziere style water pumps where the electric motor and pump are one unit are a later thing
