[QUOTE=Dansy;12645033the filter if used should always be after the Pump....[/QUOTE]
Really?
JetsMunt, I have a100, say no.
XiCoy, I have a X45, say no.
AMT , I have two, Olympus and Pegasus do not have a filter AFTER the the pump.
Might I suggest you follow the manufacturer.s recommendations.
In the case of the superb little X45 Gaspar says NOTHING Between the pump and engine.
He probably knows best.
