Where to buy

This is a Moeller in-line disposable fuel filter, part number 033316-10, with 5/16 inch barbed connections. Its job is to trap dirt and metallic particles in the fuel line, and it is a disposable design. The vial is clear, so the condition of the fuel can be inspected directly. The maker states plainly that it is not for use with inboard engines, so confirm what your engine setup is before choosing it.

Our take

The clear vial lets you look at the fuel's condition directly, which is a handy extra on a filter whose job is catching dirt and metallic particles. The maker says it is not for inboard engines, so check your engine type first.

From our buying guide

Parker lists Racor's marine Turbine Series for diesel and biodiesel engines, and Racor says gasoline filters in an enclosed location should use a metal bowl. A micron rating means little without its efficiency.

Check before you buy:

  • The efficiency is stated with the micron size. Racor labels its finest element 2 micron and rates it at 98% at 4 microns.
  • You know your engine's change interval, since intervals are per model.
  • You can fit it on the suction side of the fuel transfer pump, where Racor says to install its 900MA and 1000MA, since pumps emulsify water.
