Filter Pressure Drop Gauge
From January 99 Mainsheet

This might be a good time to bring up the issue of fuel filters. Either we clean them regularly (and most of us probably do not) or they slowly clog up and interfere with proper flow to the engine, maybe when the engine is most needed! It would take only one bad batch of fuel to clog the filter.

Consider adding a fuel suction meter in the line between tank and fuel pump. This meter will give you an absolute indication of the pump suction required to bring fuel from the tank. Mark the pressure with a clean filter and, when it increases, check the filter. The cost of installation and parts was about $120.00. It can be tee’d into the fuel line anywhere and does not require fuel system bleeding. Not too bad for peace of mind whilst at sea.
