Scepter Marine Primer Bulb — 07813
The Scepter 07813 is a marine fuel primer bulb with 1/4-inch (6.35 mm) hose barbs. Its high-flow design and dual internal check valves help prime the fuel line and reduce backflow leakage. Construction is gasoline- and solvent-resistant and compatible with ethanol fuels.
Specifications
- Part Number: 07813
- Hose Barb Size: 1/4 in. (6.35 mm), for matching 1/4 in. ID fuel hose
- Internal Design: Dual check valves, high-flow priming
- Fuel Compatibility: Gasoline, ethanol fuels
- Construction: Gasoline- and solvent-resistant materials
Compatible Applications
- Marine fuel-line assemblies requiring a primer bulb with 1/4 in. hose barbs
- Replacement of hard, cracked, or failed primer bulbs in compatible systems using 1/4 in. ID fuel hose
Fitment — Verify Before Ordering
- Confirm your fuel hose inside diameter is 1/4 in. (6.35 mm) — this bulb is not interchangeable with different sizes such as the Scepter 07494 (5/16 in.)
- Scepter produces visually similar primer bulbs across multiple hose diameters — always measure the fuel hose ID, not the hose OD
- Confirm existing fittings and tank connectors are compatible with your engine and fuel tank
- Verify the primer bulb flow direction arrow points toward the engine after installation
When to Replace
- Bulb has become hard, cracked, or permanently collapsed and will not return to shape
- Bulb squeezes but will not firm up during priming
- Fuel drains back toward the tank between uses
- External fuel leakage is visible at the bulb body or hose connections
- Internal check valves no longer hold prime after repeated squeezing
- Hose-barb connections are damaged, cracked, or weeping fuel
Installation Notes
- Confirm hose ID is 1/4 in. (6.35 mm) before installation
- Install with the fuel-flow arrow pointing toward the engine
- Push the fuel hose fully onto each barb until seated against the bulb body
- Secure each hose end with an appropriately sized marine fuel-line clamp
- Route the bulb away from exhaust heat sources and abrasion points
- Prime the system fully and inspect all connections for leaks before starting the engine

Parts Desk Insights
Best Use Case: Replacing a failed primer bulb in a compatible marine fuel-line assembly using 1/4 in. ID hose. Confirm the hose size, existing fittings, and engine and fuel-tank requirements before ordering.
Common Issue: Selecting a primer bulb by appearance or engine size rather than matching the fuel hose inside diameter can lead to an incorrect fit. Check the hose size and part number before ordering. The 07813 has 1/4 in. hose barbs; a different barb size is not a substitute.
