I am trying to reinstall the vacuum tank on my 1998 Dodge RAM 1500 5.2 L engine and there fore need the vacuum hose diagram.

Here is a general vacuum hose and line placement diagram for a 2001 Dodge Ram 1500 4x4:

1. The vacuum line from the engine intake manifold should be connected to the vacuum reservoir tank.
2. The vacuum line from the vacuum reservoir tank should be connected to the vacuum actuator on the front axle.
3. The vacuum line from the vacuum actuator on the front axle should be connected to the transfer case.
4. The vacuum line from the transfer case should be connected to the vacuum actuator on the rear axle.
5. The vacuum line from the vacuum actuator on the rear axle should be connected to the vacuum reservoir tank.

It is important to note that the specific placement and routing of vacuum hoses and lines can vary depending on the make and model of your Dodge Ram 1500, as well as any modifications that may have been made to the vehicle. It is always recommended to refer to the manufacturer's instructions or a repair manual specific to your vehicle for accurate information. Additionally, it may be helpful to take pictures or label the hoses and lines before removing them to ensure proper reinstallation.

Vacuum what?, HOSES? or all intake plenum vac things.????
well there are not many vacuum devices on cars now.
5.9L engine
there is the brake booster, vacuum huge hose, easy to figure out.
then EVAP CAN.,, bingo for VAC hoses !
FPR hose? ,no it is part for top of fuel pump RACK at tank.
not tank vents hoses right? the other side of the EVAP system.
EGR valve? is bolt on,.yes vac,no hoses.
the service manual covers this.
is this a post collision question
or bought truck with no engine question, be nice to know how bad this is. (the story missing)
the IAC is vacuum but simply bolts on , no hose there.
The Throttle body is also VAC device bolt on to plenum intake man.
the MAP sensor is again VACUUM bolt on ,no hoses.
why not tell what is missing, see vacuum ports open?
hoses dangling? if yes,what does other end go to, bingo ,

In the engine compartment, locate black vacuum hose that runs from brake booster check valve to intake manifold, there will be a small vacuum hose attached to check valve at the power brake booster check valve. This is the vacuum line going to the heater control unit,check the hose all the way to the firewall, repair any leaks you find. And that should take care of your problem.......GOOD LUCK

You didn't mention engine size, so i have included diagrams for all 3 available engines...

WELL YOU HAVE TO DROP THE FUEL TANK TO ACCESS THE TOP OF IT, USE A PUNCH AND HAMMER TO REMOVE THE LOCKING RING AND LIFT THE PUMP OUT OF THE TANK.BE FORE YOU DROP THE TANK YOU MUST REMOVE THE RUBBER FILL-NECK HOSE AND VENT HOSE. AND WHILE LETTING DOWN THE TANK AFTER UNBOLTING THE STRAPS, YOU MUST UNPLUG THE PUMP WIRES AND FUEL LINES. SORRY TO SAY BUT THIS IS A LONG JOB AND REQUIRES THE USE OF A FLOOR JACK AND A PLANK THAT SPANS THE TANKS WIDTH. HOPE ALL THIS INFORMATION IS USEFUL. BEST OF LUCK TO YOU. BE SAFE WHEN DOING THIS PROCEDURE.
