Suction Set Overview
Buy Titan EPX2505 Low Boy Suction and Return Components
The Titan EPX2505 Low Boy Suction Set connects the coating material supply to the sprayer's fluid section and provides a separate return pathway used during priming and fluid circulation. The suction tube and return hose perform distinct but complementary functions.
The siphon tube draws coating material from a container toward the pump inlet. The return hose directs material from the bypass or priming circuit back toward the supply container. Together, these components support the material flow required for priming, circulation and normal spraying operation.
Over time, suction tubes and return hoses can develop damage, blockages or connection problems. Replacing a defective component can help restore proper fluid movement when the underlying problem has been identified.

REF. 1 | FLUID RETURN
Titan 800-903 Return Hose
The Titan 800-903 Return Hose carries coating material through the sprayer's return circuit during priming and recirculation. It is an important component for directing fluid back toward the material container when the sprayer is in the appropriate operating mode.
Inspect the return hose for cracks, kinks, deterioration, obstructions or damaged connections. A leaking or restricted hose may interfere with normal return flow and create unnecessary cleanup or service problems.
Current Part Number: 800-903
Replaces: Titan 507964
Diagram Reference: 1
REF. 2 | MATERIAL INTAKE
Titan 0507965A Siphon Tube
The Titan 0507965A Siphon Tube provides the material intake pathway from the coating container to the sprayer's fluid section. Maintaining an unobstructed suction pathway is essential for effective priming and continuous material delivery.
A damaged tube, restricted intake or loose suction connection can allow air into the material pathway or prevent sufficient coating from reaching the pump. Inspect the siphon tube and its connections when diagnosing weak material pickup or repeated loss of prime.
Part Number: 0507965A
Component: Siphon Tube

Material Flow
How the Titan EPX2505 Low Boy Suction Set Works
Material Pickup
The siphon tube extends into the coating supply to provide a material intake pathway.
Pump Intake
The fluid section draws coating material through the suction pathway as the pump operates.
Priming and Return
During priming, material flows through the designated bypass circuit and return hose.
Spraying Operation
When switched to spray mode, the sprayer directs pressurized material toward the spray hose and gun.
Replacement Part Number
Titan EPX2505 Return Hose Part Number Cross-Reference
The AllTitanParts listing identifies the following replacement relationship:
- Titan 800-903 Return Hose replaces Titan 507964.
If your original EPX2505 suction set documentation lists part number 507964, review the current Titan 800-903 product listing. Always verify the correct equipment and assembly configuration before ordering.
Troubleshooting Guide
Common Titan EPX2505 Low Boy Suction Set Problems
| Problem | Components to Inspect | Recommended Check |
|---|---|---|
| Sprayer will not prime | 0507965A Siphon Tube | Check material level, intake restrictions, suction connections and inlet valve condition. |
| Sprayer repeatedly loses prime | Siphon Tube and suction connections | Inspect for air entry, loose connections or damage to the suction pathway. |
| Return hose leaks | 800-903 Return Hose | Inspect for cracks, wear and damaged hose connections. |
| Little or no material returns during priming | Return Hose and bypass valve | Check for obstructions and verify proper priming valve operation. |
| Uneven material pickup | 0507965A Siphon Tube | Inspect for partial blockage, air ingestion and material supply problems. |
| Visible paint contamination | Material supply and suction pathway | Check container cleanliness and any applicable intake strainer or filter. |
| Material continues returning in spray mode | Bypass valve and return pathway | Diagnose the PRIME/SPRAY valve before replacing the return hose. |
Parts Selection Guide
How to Order the Correct EPX2505 Low Boy Suction Set Part
Verify Your Sprayer
Confirm that your equipment is the Titan EPX2505 piston pump.
Confirm the Configuration
Identify the low-boy suction set rather than an upright cart intake arrangement.
Match the Part Number
Select Titan 800-903 for the return hose or 0507965A for the siphon tube.
