The Advantage 400 main assembly diagram lists 14 parts: the motor cover, fluid section assembly, suction set assembly, siphon tube, inlet screen, legs, return tube and fasteners. It is the top-level page. For the parts inside, open the fluid section, gear box, motor, suction set, stand or cart diagram. The EPX2155 has its own set of pages with some different part numbers.
The Advantage 400 in brief
The Advantage 400 is an electric piston sprayer. One dealer describes it as the EPX2155 reborn as the Titan Advantage 400. Titan lists it at 0.47 gpm with a maximum tip of 0.021 in. and a 0.75 hp DCX motor, and describes a sleeveless fluid section with stationary packings, so there is no cylinder to wear or replace. We leave out its pressure and weight, because the sources disagree on both. The sections below follow the diagram, not the spec sheet.
Main assembly: the numbered parts
The Advantage 400 main assembly page is the overview. It shows how the sprayer goes together and links the big assemblies. Most of what it lists is a larger assembly that has its own diagram.
Advantage 400 main assembly: the key parts and where each leads

| 0552754 | Fluid section assembly | Fluid section page |
| 0558672A | Suction set assembly | Suction set page |
| 705-054 | Siphon tube | Part of the suction side |
| 710-046 | Inlet screen | The suction side |
| 704-117 | Fluid section screw | Fastener for the pump |
| 0551524 and 0551526 | Right and left leg assemblies (the left is marked stand only) | Stand page |

The page also lists a return tube (0551556, cart only), a hose tie clamp, a pail bracket bolt and fasteners.
Following the part to its own diagram
Once you know which assembly the part belongs to, go to that page. The Advantage 400 pages on the site are:
- Fluid section (32 parts): the pump end, with the piston rod, valve balls and seats, and seals.
- Gear box (26 parts): the 9850936 power switch, 700-771 pressure control knob, gears and thrust washers.
- Motor (8 parts): the 0551540 motor assembly, motor fan, capacitor assembly, fan shroud and the 0508645 brush kit.
- Suction set (9 parts): the 0558672A suction set assembly, the 700-805 inlet screen filter and the 0558659A return tube.
- Stand (10 parts): legs, drip cup, plugs and fasteners.
- Low boy cart (14 parts) and upright cart (4 parts): wheels, spacers, hub cap and handle hardware.
Page counts are the number of parts the site lists on that diagram. Our page does not list everything on your sprayer, only the parts we sell, so a part missing from the page may still exist on the machine.
Fluid section highlights
The fluid section is the biggest page, so here is a quick orientation to the items buyers ask about most. A separate post covers how to tell which of these to replace, so this is only a map.

Advantage 400 versus EPX2155 diagrams
The EPX2155 is the earlier name and it has its own diagram set, starting from the EPX2155 main assembly page. The pages look alike, but they are not identical lists. The Advantage 400 fluid section assembly is 0552754, and the EPX2155 one is 0551529. The suction side differs as well: the EPX2155 lists a 0551437 siphon tube assembly and a 0295565 inlet filter, where the Advantage 400 lists 0558672A and 700-805. The 0551540 motor assembly appears on both motor pages.
So treat the two diagram sets as separate. Use the set that matches the name on your sprayer, and do not assume that another EPX model such as the EPX2255 lines up with Advantage numbers. We do not map those. The broader Advantage sprayer parts and SprayTech Advantage EP and EPX pages list the others.
Which stand or cart you have
Three frame styles appear in the diagrams: a stand, a low boy cart and an upright cart. Look at how yours is built. Legs without wheels point to the stand page, and wheels point to one of the cart pages. Parts marked stand only or cart only on the main assembly page apply to one style, such as the left leg assembly (stand only) and the return tube and clip (cart only). If you are not sure which you have, call (713) 931-0006 with your model label and our parts team can tell you.

The Short Version
Use the main assembly page to name the assembly, then open its own page for the individual part. Keep to the Advantage 400 set or the EPX2155 set according to the name on your sprayer, since some part numbers differ.
