Sunkissed Tropical Tanning

We are in the process of trying to get a Magic Tan 2000 working correctly. As of now it appears that it sprays fine (all 3 banks) but when you purge only a couple of nozzles in each bank have water coming through them. We have taken all the nozzles out and cleaned them which helped but not all of them work when being purged. My question is can it be that the "filter" between the solution line and the actual nozzle is clogged? We made sure that air was getting through them when we cleaned them but still could use some help. We have hooked up solution to the machine and sprayed ourselves but the color we are getting is very light. We checked all the solution and air settings and they are right where they are supposed to be. Any help will be appreciated.
