VACUUM GAUGE



Racor vacuum gauges can be had for about $80.00, so the condition of fuel filter elements can be monitored. Any old vacuum gauge will work. This Wika gauge costs little compared to the Racor gauge.

While the gauge could be used to measure dirt loading of the element, to decide when to change the element, we use it only to make sure the element is not fully loaded causing a restriction in fuel flow. The element is changed about every 100 engine hours whether it needs it or not. Racor suggests 10 inches Hg as the point to change the element if you are using a gauge to determine when to change the filter.

Just a note to wish you well, again. Vanessa and I will be following you with enthusiastic envy.
May your vacuum remain always below 10 inches
