Fuel sampling port

[Dave J]

My fuel sampling port is between the fuel cell and the low pressure side of the fuel pump. Will this set up pass an annual tech inspection?

[BLS]

The rules require that it be located between the fuel cell and carb, so it would satisfy that requirement. However, I'm of the opinion you would be unable to produce a sample this way since it is on the suction side of the pump. Mine is between the pump and carb.

mine is on the low pressure side and just a bit of air pressure on the vent line will allow fuel to flow out the sample line without starting or cranking a hot engine. My vent line is long enough to pull out and blow on. It looks a bit funny but impresses the tech folks since there's a much reduced chance of fire.

[Matt King]

That's a good trick. I had mine on that side of the system but I could never get a sample to flow, so I moved it to between the pump and carb.

Mine is on in my tool box
