Inspect the Intake Hose and Lower Fluid Section

problem is just removing this hose, looking up inside there at the lower ball. And on a 440i, it just has a retention spring. This retention, usually you can just grab them with two fingers, squeeze the spring, and it'll just come right off. This one's got a one side of the spring's broken, so I'm using a pair of needle-nose pliers to just squeeze that spring together and pull that spring down. on. And this little retention spring is what keeps this hose up inside the lower fluid section. Once you remove that spring, lower fluid section hose will come out. Look down inside this hose. A lot of times you'll see a big chunk of paint down inside this hose. If not, now you're going to look up inside this lower fluid section and you'll actually see a ball up inside there. And you'll typically I've actually seen blades of grass in between that ball not passing through there. I've seen little tiny sticks up inside there, but most commonly uh thin pieces of film breaking free from that hose. And then you just reach up inside there. I use just like a little tiny flathead screwdriver. Anything that will reach up inside there. Sometimes a five in one can grab it. Or you can just use a little pair of needlenose pliers. Reach up inside there. The needle-nose pliers is actually long enough to touch that ball and actually grab anything, keeping that ball from receating down and allowing paint to pass and not pass properly. And you'll just get that whatever's debris is in there that's causing your issue. Pull it out. You're going to stick your prime, you're going to stick your fluid hose back on and it should cure your problem. And I'll show you what that ball looks like here closely. We'll get a close-up view with our camera. So, we're looking inside our lower fluid section, and you can actually see that ball inside there. And that ball has got to be able to move up and down and be able to allow paint to go flow through
