Thanks again for the help. It turns out the problem was my stupidity. I bought another fluid tip for the gun to use for clear-coat. However, the gun didn't pick up paint from the cup with it. I thought I had gone back to the original fluid tip for troubleshooting purposes, but for some reason it was still the new tip. Once I finally realized that, I put on the original fluid tip and it worked great. Turns out even though the tips look almost identical, the new tip wouldn't work with a suction feed cup. The end result is I painted both the base coat and clear coat with the original tip (1.6) and it worked great. I made sure I adjusted the compressor for the PSI recommended for the base coat and clear coat (different settings). FYI: this is my third attempt to paint the truck (sanded down the first two). The first time I used a HVLP/turbine system and the second time a HVLP gun with the air compressor (different guns). The third time (this gun), I used a regular gun with my compressor. This time the results were great. I couldn't get rid of the orange peel with the first two systems. It may be I just wasn't skillful enough, but the regular gun worked great for me and clean-up was much simpler than the HVLP guns. Again, thanks for the responses. One of my troubleshooting rules is "go back to the thing you did last." I should have known.
