Racor as Final Filter on Pressure Side?

[Troubadour52993]

My installation has a Racor 230 filter near the tank as the primary filter for all fuel. The Perkins main has a Perkins final filter element on the engine after the lift pump, but the Perkins generator has a Racor 220R filter in line after the lift pumps - a small NAPA electric pump, then mechanical pump, then filter, then injection pump.

I know the Racor literature says the 220R should be on the suction side, and I know it also says that it should take up to 7 psi. When the genset is running, there is a slight drip from the bowl plug where the water detector option goes.

Should I replumb this in front of the lift pumps, get a new final filter rated for a higher pressure, or replace the gasket on the plug & keep on chugging? Anyone know what the pressure output of a typical pump is?

Thanks, Chris

You want the primary filter (Racor 230) before the priming fuel pump to protect the pump. This means your primary filter will end up on the suction side as the instructions call for.

while you are replumbing put a vacume gauge on that filter one with a second captive needle so you will know when its time to change it or if your motor problem is a cloging filter. racor does not make captive needel units to my knowlege but they are available you will have to adapt the thread size to racor to plumb.

Replace the gasket. What you have is fine and can be found on many boats.

Thanks fishwife, I changed the o-ring under the plug when I removed the bowl to change the filter. 3 days now with no leaks!

Just went to boat show seattle and discovered that racor now makes captive needle vac. gauges. not much use on pressure side
