Transparent fuel hose makes it possible to visually inspect the fuel inside the line during service.
Depending on the application, this can help identify:
- Whether fuel is present in the line
- Obvious air pockets
- Fuel-flow interruptions
- Visible contamination
- Line deterioration or discoloration

View Oetiker Clamp PackChoosing the Correct Tygon Hose Size
Tygon hose should be matched to the fitting and fuel-system application. Item 257 has a 1/4" inside diameter.
Do not substitute a 3/16" or 5/16" hose simply because the fitting appears close in size. The hose must fit the fuel-system connection properly and match the original application.
When Should Tygon Fuel Hose Be Replaced?
Inspect small fuel lines during normal fuel-system maintenance. Replace hose that shows signs such as:
- Cracks or splitting
- Hardening or brittleness
- Fuel leakage
- Loose hose-to-fitting connections
- Severe discoloration or deterioration
- Abrasion or routing damage
