⚡ At a Glance
  • Build Quality: Hand primer bulb with a built-in check valve, 3/8-inch fuel hose and 360° stainless steel hose clamps for secure connections
  • Best for: Boat owners, motorhome users and small agricultural vehicle operators seeking reliable manual priming
  • Not ideal for: Systems that require integrated electric priming or proprietary factory-fit hoses

Hand primer bulb includes a built-in check valve and attaches to a 3/8-inch fuel hose. Low-permeation construction meets EPA low-permeation mandates and helps reduce fuel vapour loss.


Reliable manual priming - with a hand primer bulb and built-in check valve

Hand primer bulb incorporates a built-in check valve that prevents backflow and draws fuel toward the engine during manual priming. The arrangement reduces the chance of air entering the line while pumping.

Quicker, more consistent starts with fewer pulls and less bleeding of air from fuel lines.

Reduced fuel vapour loss - with low-permeation fuel line construction

Low-permeation hose construction is specified to meet EPA low-permeation mandates and is compatible with blended fuels. The construction reduces fuel molecules passing through the hose wall.

Less fuel evaporation and lower emissions, helping preserve fuel and meet regulatory expectations.

All-weather durability - with temperature-stable bulb and hose materials

Bulb and hose are described as maintaining flexibility and resisting collapse across extreme hot and cold temperatures. Materials remain pliable to preserve function when exposed to varying climates.

Reliable performance year round without hardening or collapsing, suitable for marine and RV conditions.
