Graco Magnum DX Spray problems

Just before I stored my spray away for awhile I was hearing my pump double pumping.

I had added 50ft hose on to my sprayer which already had a 25ft hose. So what I am trying to say is I have a 75ft hose and I was running water through it and it started double pumping, now it never did this before.

Is there something else going wrong with the internal parts or was this just a fluke.

The reason I am asking is because I just got a job that I have to use my sprayer.

Any help will be much appreciated.

That is a smaller sprayer and it is prob. just trying to keep up with the new weight, remember that paint weighs a lot and that it has to push it through the line. I used to have a gravity fed Wagner that would choke a bit if I even went up a ladder.
