im new to the site and to the sc400 useto have a is300 but anyway the 2 vacuum lines off the intake manifold i need to know wherethe larger hose goes to please and thank you.sorry if i posted in wrong thread.

 

the air intake? there should be a diagrahm on your hood i believe

 

theres no sticker on my hood its in the front where the lexus emblem is the it routes to the passenger side of the car and down the side of the motor then i dont know from there

 

it goes to the power steering pump, i capped it because the line connects to a plastic peice that was leaking ps fluid. apparently it helps with turning at high speeds because the plastic peice also has a line that is connected to the air intake . I havent noticed a difference since its been capped

 

Post up a pic

 

here the hosue im talking about on a side note anyone know how to remove this cap and where to get a new one?its spraying out anifreeze.[ATTACH][/ATTACH]

 

The bottom picture you are missing the sensor. I know that some tanks have them and some don't. Do you have a plug near there that is just laying there or unplugged?

 

i dont know but ill check and the house thats zip tied goes to the power steering pump?

 

I checked could not find it where does the wire come from?its a 92 sc400 do you know if it came with a sensor or no or is there a way for
Me to check?

 

Can anyone answer this?
