The Multiquip 29338 Primer Bulb 5/16 Hose Barb is a genuine OEM component designed for Multiquip PS, SP, and CS series pavement saws and KD series core drills. As a direct OEM replacement, 29338 delivers an exact match to the original part — no adaptation needed to restore proper fuel priming function. Confirmed fitment spans a wide range of models including PS403016, PS403020, PS403030, SP403016, SP403020, SP403030, CS403016, CS403030, PS706016, PS706030, KD1800, KD6, and KD1800KD6, among others. Sourcing the correct primer bulb with the right 5/16 hose barb sizing is critical to maintaining a leak-free, reliable fuel system on your saw or drill.
Key Features
- Correct 5/16 Hose Barb Sizing — Matched to the original hose barb diameter so the bulb seats and seals properly against the fuel line without leakage or air infiltration.
- Genuine OEM Part — Manufactured to the same material and durometer specification as the original, ensuring the bulb compresses and rebounds correctly through repeated priming cycles.
- Broad Saw and Core Drill Compatibility — Fits PS, SP, and CS pavement saw families as well as KD1800 and KD6 core drill models, covering a wide range of Multiquip cutting equipment.
- Restores Clean Cold-Start Performance — A degraded primer bulb introduces air into the fuel circuit, causing hard starts and rough running; replacing it with this part restores a consistent fuel prime every time.
- Fuel System Integrity — Because this component is part of the fuel delivery path on gasoline-powered cutting equipment, using a correctly rated OEM bulb helps prevent fuel seepage around the barb connection.
A primer bulb is a small, manually operated pump built into the fuel line between the tank and the carburetor. Squeezing the bulb draws fuel forward into the carburetor circuit, displacing air and allowing the engine to fire quickly — especially after sitting idle. Over time, the rubber compound in the bulb hardens, cracks, or loses elasticity, causing it to collapse without springing back or to leak at the hose barb connection. When that happens, cold starts become difficult, the engine may run lean under load, and fuel can seep onto hot engine surfaces — making timely replacement important for both performance and operator safety.
