hilux_1990 Posted March 29, 2004 Share Posted March 29, 2004 Since I 'upgraded' to an L-series I have been wondering about the purpose of a certain hose, connected to the air filter box, that doesn't go anywhere... It is just a right-angle hose, same size as the PCV hoses, and the inlet inside the filter box is covered by a rubber flap while the other end is uncovered and finishes above one of the cam carriers. Just wondering what it does? thanks... Quote Link to comment Share on other sites More sharing options...

hilux_1990 Posted March 30, 2004 Author Share Posted March 30, 2004 I've seen it on the air filter boxes of two carby EA-82's. I would think that the suction inside the airbox would make the engine breath in air through this extra hose as well? Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted March 30, 2004 Share Posted March 30, 2004 it goes nowhere, except your bucket of parts, remove it the drain is a hole in the front of the air box which pic could you not open? iirc, you can remove the componets marked with red Quote Link to comment Share on other sites More sharing options...
calebz Posted March 30, 2004 Share Posted March 30, 2004 One of them there battery cables in your pic is marked in red.. do you think it would be wise to remove it? Quote Link to comment Share on other sites More sharing options...
Snowman Posted March 30, 2004 Share Posted March 30, 2004 What is that plastic fitting with the red mark on it that is attached to the PCV system? That has confounded me for quite some time. Quote Link to comment Share on other sites More sharing options...
archemitis Posted March 30, 2004 Share Posted March 30, 2004 that little hose next to the strut tower is a vent hose for the fuel system, or a return line, leave that, the other bigger ones going into that square box, is you ari suction valve system. you can remove those hacksaw the pipes off and weld them shut. or just stick a sparkplug down the biggest hose, and its blocked off.
