My 3M gun has a small funnel part on the nozzle where the disposable cup attaches. I just fill that with lacquer thinner a couple times and spray it thru the gun. I don't know how big the adapter is on your HF stuff, but maybe a few fills of thinner in that would work. I use a small poly bottle with a squirt top to fill it. The attached pic shows the 3M Gun & Nozzle with the cup attached. When the cup is removed, the orange part stays in place and can be filled with thinner. All it takes is 2-3 ounces of thinner and the gun is nearly clean. Taking the nozzle (the orange part) off and wipe down the needle and you're done.
