As
careful as I am when changing fuel filters, I often get air into the
system and have to bleed the engine. Is there anything on the market
that can prevent this? O.H., via e-mail
Racor
says its P Series diesel fuel conditioning modules can eliminate air
from the fuel system and also prime the filters with clean fuel. The
diagram shows the unit installed between the fuel tank and fuel-water
separators. On twin-engine applications, two modules are used.
Once your filters
have been changed and you wish to prime the engine, engage the electric
primer pump via a switch, and fuel is drawn into the unit from the tank
and into your filters. After priming, you merely shut the switch, and
your engine’s fuel delivery system is ready for normal operation.
In addition, a sensor
indicates when it is time to drain the unit. When that happens, merely
place a bucket under the drain plug and empty the accumulated water
and other materials, making sure to dispose of them properly. The filter
element should be changed each season or every 100 hours, or if you
notice any loss of horsepower.
The P Series comes
in three flow rates of 30, 40, and 50 gph, and the anodized die-cast
aluminum housing has 3/8-inch NPT ports for the fuel lines. The current
design calls for installation outside of the engine room. More information
