I bought a 52mm generic electronic boost gauge but don't know where to tap the air tube into.

I tried to find a thread on a boost gauge install, including the TRD boost gauge manual, but to no avail, (even tried google). The most information I found is that there is a port to "T" off of behind the supercharger. Not sure how you would do this if you're not using the TRD boost gauge.

I would greatly appreciate any help.

 

What does the tube end of the generic guage you bought look like? That's really what matters; you want to T it to the boost port on the SC like you mentioned, but it must be air tight.

 

I am assuming you bought the truck with the SC installed, so it's probably harder for you to figure things out. Also, depending on who installed the supercharger, they might have used different ways of hooking up the vacuum lines, which might change what your are seeing in your engine bay. Is there anyway you could take some pictures of your engine (specifically behind the S/C) to help us help you?

 

You can see my boost port and lines in this pic. It's right below that big hose on top. You can see I have 3 tees coming off the boost port and the last tee wasn't connected yet when this pic was taken but it has the blue caps on the end of it.


I have a couple hard plastic lines running into the cab for the boost gauge, FTC, and A/F calabrator.

 

Thanks for the responses guys.

MT- Just what I was looking for! Big help buddy. Thanks a bunch.

 

Well, it has to be mounted between the compressor (S/C) and the engine. Then it will read vacuum and boost., If you install it before the S/C, you will only see vacuum.

 

MT,

Does the brass nipple that comes out of the boost port come with the supercharger?

Does the brass nipple come with a TRD boost gauge?

I have a plug in the back of my 2nd gen S/C where there should be that 90 deg brass nipple.

 

This is the part I need in the attached picture, (Part B). In MT's picture it is a 90 deg nipple.

 

The ones I've done, it came witht he supercharger.

 

The 90 deg fittting came from Ace hardware. The SCer came with a straight fitting but my heater hoses interfered with it, so I changed it.

 

Thanks guys. I'll try to find the right fitting at Ace.
