Key Features
- Genuine OEM Construction — Produced by Wacker Neuson to the exact material and dimensional specs of the original primer, ensuring consistent fuel draw and seal integrity across its full service life.
- Direct-Fit Replacement — Engineered to drop into the existing fuel system connection point with no rework to lines or fittings required.
- Broad Compaction Equipment Compatibility — Fits the RS800H single-drum roller, DPS3050 and DPS3060 single-direction vibratory plates, and the DPU 2870, DPU 2950, DPU 2960, and DPU 2970 reversible vibratory plate series.
- Consistent Cold-Start Performance — A functioning primer delivers the correct fuel charge to the carburetor before startup; a cracked or failing primer leads to hard starts, extended cranking, and incomplete fuel delivery.
- Fuel System Integrity — The primer bulb forms part of the sealed fuel circuit; a degraded unit can introduce air into the fuel line, causing lean-running conditions or stalling under load.
A primer — sometimes called a primer bulb — is a small hand-operated bulb fitted in the fuel line between the tank and carburetor. Squeezing it manually draws fuel from the tank and purges air from the line, giving the carburetor a wet charge of fuel before the engine is started. This is especially important on compact compaction equipment that may sit between uses, allowing fuel to drain back to the tank. When the primer hardens, cracks, or loses its check-valve function, the engine becomes difficult or impossible to start cold and may run erratically once running.
