Did not need all that was in the set, but sprayer was restored. Directions for repair would be nice.

Have had solo back pack sprayer over 20 years. Needed replacement part and worked perfectly. 1/2 price of big box store. Highly recommended.

Old seals were leaking everywhere. Took about 20 mins and had them all replaced and back together and that was my first time. Works perfect just like new!

Received on time, well packaged, as advertised. Fit the target sprayer and reasonably easy to install. Stopped piston leak, which was needed. Being more careful to clean sprayer and leave a detergent residue for protection, and lubricate a bit more often as well. Plan to partially rotate parts annually to spread long-term gasket and ring wear due to slight eccentricity of piston assembly when operated. Seems to be a normal condition for manually operated sprayers. Not sure about motor units.

Parts fit properly, quick shipping
