You can get the purge solenoid from the donor car, and hook up a 12 volt timer relay that turns off after about 1 minute.
The problem here is that usually anything that had a cannister had a computer with a purge programmed into the engine computer.
Maybe you could find an electronic timer diagram on the internet and build your own from the instructions.

The next obstacle is that you have to have a vent valve that would let air in as the vacuum in the manifold sucked it out.
The timer could open the purge solenoid and the vent valve at the same time.

Today's cars run a program that cycles the purge solenoid about 20 times a second so the engine does not see a big vacuum leak. You would be essentially designing your own system, so you would understand why you have a high idle when you first start up the truck.
Parts typically wouldn't run over $15
