What This Bleed Hose is Used For
Sierra 8050 is used in compatible marine engine applications requiring 1/16" ID bleed hose.
Depending on the engine, small bleed lines can be used within fuel, lubrication, induction or crankcase-routing systems. Their exact function depends on the engine design and hose location.
Always verify the original hose diameter and applicable OEM number before replacing an existing line.

What This Bleed Hose is Used For
Small-diameter bleed hose is used in compatible marine engine systems to connect bleed fittings and route fluid between engine components.
The exact location and function depend on the engine. On many marine engines, bleed-line circuits are part of the engine's fuel, lubrication or crankcase routing system.
Because the same hose diameter can be used in different locations, always verify the original hose size and OEM part number before installation.
This hose has a 3/32" inside diameter.
Bleed hose must fit tightly on the intended fittings. Do not substitute 1/16", 1/8" or another hose diameter simply because it appears close in size.

Transparent Tygon Bleed Hose
1/8" Tygon Bleed Hose - 10ft Length
Pro Marine Item 259 is transparent 1/8" Tygon bleed hose supplied in a 10-foot length. It is used in compatible marine and PWC applications requiring small-diameter bleed line.
The transparent construction makes it easy to visually inspect fluid inside the hose, which is especially useful when servicing bleed, oil-related or other small fluid-line circuits.
Pro Marine also stocks several other Tygon hose sizes for fuel, oil-injection and bleed-line applications. Use the size chart below to compare the available options.
Inside Diameter: 1/8"
Length: 10 Feet
Material: Tygon
Color: Transparent
Application: Bleed / Small Fluid Line
Item Number: 259
What This Tygon Bleed Hose is Used For
Item 259 is intended for small-diameter marine applications requiring 1/8" transparent Tygon bleed hose.
Small bleed lines can become brittle, cracked, loose or damaged over time. Replacing deteriorated tubing helps maintain proper fluid routing and system operation.
Always verify the required inside diameter and application before replacing an existing hose.
Why Use Transparent Bleed Hose?
Transparent hose allows the line and the fluid inside it to be visually inspected during service.
Depending on the system, this can make it easier to identify:
- Whether fluid is present in the line
- Air pockets
- Visible contamination
- Flow interruptions
- Hose discoloration or deterioration

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
