I have a Quicksilver water separaing fuel flter to install with the rest of my tune up kit. Does it matter where the filter is located?<br /><br />1988 GM 3.0L 4cyl (181ci)<br />Mechanical fuel pump mounted on the block driven by the engine.<br /><br />Mount:<br />Before the pump?<br />After the pump?<br />If before the pump (which I think) does height matter in relation to pump?<br /><br />Thanks
