Ok i was going to put the sea foam in today. I started it up and took the brake booster hose off. The truck started sputtering and it was wanting to die. I tried to rev it up put it just kept sputtering worse and finally died. Is it suppose to do this? I haven't put any in yet. I was just wanting to know if this is normal? It would barely run with the hose off

Yea, it's gonna want to stall with the booster hose off since that create's a huge vacuum leak. You can try cracking the throttle a little bit (use a screwdriver or matchbook wedged between the set screw) to keep the RPM's up while you do it.

find a smaller vacuum hose

Put your thumb over the open end of the brake booster hose to create a small opening and slowly pour the can down into the hole...The vacuum will suck down the fluid so it will not spill everywhere.
