Power Steering hosing

Recommended Posts

Can someone have a look at the pic please, the banjo bolt connected to the power steering pump has 2 feeds coming off it as you can just about see in the picture. One of those feeds is going to a T-Piece with one side of it blocked off and the other going to the boost gauge :blink: This doesnt make any sense to me at all to why its like this. Boost gauge doesn't read anything which is how I noticed this. :taped:

I tapped my feed for my defi boost gauge into one of them but it doesnt read anything on the gauge when car is running

 

Could i tap into one of the feeds on top of the intake manifold at the rear (think there is 4 there altogether)

The two hoses go to a mechanical valve that opens as the pump loads up, letting a bit more air past the throttle body. It's an old skool way to compensate for the load on the pump if the steering wheel is turned at idle. Not a great place to T in a boost gauge. You're better off using the feed off the brass barb on the engine side of the intake manifold.
