Compatibility / Fitment Guide
Use only where the complete installation accepts 10 mm (3/8 in) ID hose. Measure the barbs on the tank connector and engine connector; brand or horsepower does not identify the hose diameter.
| Portable-tank systems | Suitable for external/above-deck low-pressure feeds when the hose marking and local installation rules permit. |
| Connector matching | Tank-end and engine-end fittings are not supplied. Match their latch shape, sealing nose and hose-tail diameter to the tank and outboard. |
| Routing | The 1.83 m line must reach with steering and tilt at full travel, without tension, crushing or a bend tighter than the hose permits. |
| Flow direction | Install the primer-bulb arrow towards the engine and secure every hose tail with a correctly sized fuel-system clamp. |
| Not confirmed for | Enclosed/below-deck petrol installations, high-pressure EFI lines, diesel, or any application requiring a certified hose class not printed on this hose. |

Frequently Asked Questions
Will it fit Mercury, Yamaha, Honda or Suzuki?
It can be used only if the system has 10 mm hose tails and you install the correct separate brand-specific connectors.
Are tank and engine connectors included?
No.
Can it be installed below deck?
Do not assume so. Use it only where the hose’s physical certification marking satisfies the installation requirements.
How is the bulb orientated?
Arrow towards the engine.
After installation, prime the system and inspect every joint under operating conditions. Stop using it immediately if fuel odour, wetness, cracking or bulb deformation appears.
