I have an aluminum sump which holds 7 quarts. I<br>pumped out three, so now the question is, how deep does the oil pump<br>suction inlet go into the sump pan? IOWs, did the oil geyser stop<br>because I shut down the engine or did it stop because the oil pump<br>started sucking air after pumping three quarts?<br><div><br></div>David<br>'68 TR250,<br>CD8124L<br><div><br></div>** triumphs@autox.team.net **<br><div><br></div>Donate: http://www.team.net/donate.html<br>Archive: http://www.team.net/archive<br>Forums: http://www.team.net/forums<br>Unsubscribe/Manage: http://autox.team.net/mailman/options/triumphs/dlhogye@comcast.net<br></div><div><br></div></div></body></html>
