F100 fog machine possibly clogged
I have an older F100 with very little use. it has been in storage for 4-5 years. the pump works, and the heater seems to work, but not getting anything threw the heater. it acts like it is clogged up. i tried compressed air through the heater, and got very very little air out the other end. is there any other options to unclogg or will i have to purchase a new heater ?
