Mercury, Mariner fuel line

Year Models 1999 up to date

with Primer Bulb

Perfect Fuel line to use in any new boat or to replace old fuel damaged fuel lines. We use this fuel line in our workshop everyday.

  • Total length is 2.1m ( 7ft )  
  • Fits late model Mercury and Mariner outboards from year models 1999 onwards.
  • This Fuel line comes in a GREY UV Stabilised outside. 
  • Inside is braided reinforced to minimise the fuel line kinking.

The fuel line diametre is 3/8 not 5/16. This larger diametre creates a higher flow of fuel to the motor. Restricting fuel flow to an outboard is dangerous. What can happen is the outboard will run lean at high speeds. Running a outboard lean can melt your outboards piston and blow the engine up. Always make sure you use the 3/8 diametre fuel line when possible. All outboards 40hp and over should only run this size.
