Frequently Asked Questions

Yes—this is a complete, pre-assembled pump with the pressure control section, inlet/outlet valves, and the drain/prime valve already integrated by Graco.

Match your sprayer’s model & series (e.g., X5 Series E 262800, X7 Series D 262805, LTS 15 17K955, LTS 17 17K960) against the compatibility list above and confirm in your parts manual.

Often, yes. Piston packing wear or a sticking check ball can cause priming and pressure issues. A new OEM pump assembly typically restores performance if the motor/drive and hoses are in good condition.

Follow the Graco service manual for torque specs and assembly order. Keep components clean, align the drive stud properly, and torque fasteners to spec to avoid leaks or premature wear.

This kit is intended for the X5 (Series E), X7 (Series D), LTS 15 (Series A), and LTS 17 (Series A). For other models, check their parts manual for the correct pump assembly.
