Rebuild in six steps
- Clean the gun first. Flush it with the right cleaner and disconnect the air line.
- Remove the collar and air cap. Unscrew the collar at the front of the gun and lift off the air cap.
- Pull the needle. Unscrew the fluid control knob slowly so you don't lose the spring, squeeze the trigger and slide the needle out.
- Swap the worn parts. Replace the seals, springs, packing and other worn parts with the ones from the kit, one at a time so nothing gets mixed up.
- Reassemble. Oil only the needle shaft, not the tip, then refit the needle, spring, knob, air cap and collar.
- Test on cardboard. Set the fan and fluid flow and check the pattern is even before you spray the job.

FAQ
6382 rebuild kit questions, answered.
Which gun does the 6382 kit fit?
The Fuji MPX-30 compressor spray gun, in both the gravity and siphon versions.
What's in the kit?
An air distributor, needle packing, needle packing nut, spindle valve, valve spring, fluid screw nut, needle spring and fluid control knob.
Does it include an air cap, needle or nozzle?
No. Those come as a matched MPX-30 air cap set. Replace them as a set if they're worn or damaged.
How do I keep the gun in good shape?
Clean it right after every use, never soak the whole gun in solvent, and never use a wire brush. Oil only the needle shaft, not the tip.
Can you fix it for me?
Yes, if it's out of warranty. Our Rockwood Village spray centre in Mississauga repairs sprayers. Contact us to book it in. Still under Fuji's 24-month warranty? Contact Fuji Spray first, because repairs by anyone other than Fuji or its authorized agent void the warranty.
Keep your MPX-30 spraying like new.
