Fitting an oil inlet vacuum pump hose to an LN167 "98 Hilux

Recommended Posts

Hi Everyone,

I working on a 98 3.0 Ltr Hilux thats had the Vacuum hose missing for quite a while. Decided to replace but not sure of the orientation of the hose on the bottom of the vacuum pump. There is a lug and only one flat spot on the bottom of the pump but the orientation of the hose does not look correct (see picture). But when looking at the attached exploded diagram it looks as though the locating lug goes on the rounded part of the pump and the hose should be turned around 180.  Has anyone got a pic or can help regarding the correct fitting to the vacuum pump?

 Looks to me like the exploded diagram is the correct way to fit the hose.


Thank You

Welcome Steve-


Sorry no specific experience on that unit but looks to me like you want to flip that fitting 180° as you say - so the hose is heading away from the belts - that way the welded plate there is acting as a protector from the belts / pulley.

Otherwise what is the little plate for…? - locator?


Not sure if this thread can help at all? - https://au.toyotaownersclub.com/forums/topic/54653-5l-e-vacuum-diagram/


& this one is probably no use but you might get something out of it = https://www.hilux4x4.co.za/views/viewtopic.php?f=67&t=1124&start=20

Hi Gary,


Thanks for the quick response. I agree with the hose facing away from the belts. 

I will fit it the other way around, thank you
