Mechanical Gauges!!

[ShawnM]

I am putting a set of mechanical gauges in my runner 22re, temp, amperage, and oil. I want to keep my stock SR5 gauges operational so I will need to put tees in all of the sending units. My questions are where do I put the temp sensor in (under the throttle body) for the temp gauge? and what size of tees do I need for the temp and oil gauge! Thanks for your help, I have to pick these up on the way home tonite, I would normally pull the sending units for thread size but I need to drive my runner everyday!

Don't think you can use a tee for the temp sensor, most mechanical temp gauges have a pretty large sender. As for the oil, I don't know, I never did find the right fittings.

Anyone know where to get metric pipe fitting??


*that's one of my favorite sayings.

You can get a package of metric adaptors at most autoparts stores. Sun is the manufacturer. You can also contact Autometer directly. They were very helpful when I put mechanical gauges in my Cruiser. Who would have thought that Land Cruisers have some British pipe thread fittings.

In my pickup I skipped the temp gauge after I found the one I purchased had a huge sender intended for a v8 motor. The small autometer (autogauge) clusters come with a small sender which will work. I put a Vac. gauge in my cluster and still use the stock temp gauge which is still working fine. I am not sure you will have room to put a T fitting and run both temp gauges. I would ditch the stock one.

Sorry I do not remember the metric fitting sizes. Call Autometer, If you get the right person they have lots of information. Never would I have believed they had 2F engine info.

There's a blocked oil port behind the front pass-side motor mount that you could use.

I wouldnt use the sun metric adapters. They are junk. I was running autometer gauges in my truck, and the oil presser sender is a large one, and had to have an adapter for it, well this sun adapter broke off on a speedbump leaving half of the adapter in the engine. I have broke three of these adapters, i would sugest mounting the sending unit remotely. I have just got some metric adapters from autometer and they are alot more beefer.

Here is the answer I got from the tech service guys at Autometer for a 22re.

Sir,
You will need the following adapters for the installation:

2268 - water temp adapter (if electrical)

2275 - water temp adapter (if mechanical)

2269 - oil pressure adapter (works for either elec or mech)

As for the FP gauge, you would need to fabricate your own fitting, and it will need to be able to adapt to 1/8" NPT female.

The accuracy of the gauges is 2% full scale.

I am interested in installing Autometer Oil Pressure and water Temperature guages in my 1988 Toyota 4Runner with 22RE 4 cylinder engine. Do I need special adapters for the sending units for this application? (Note I already have a pillar pod to mount the guages themselves in, I'm just interested in how to tie in the SENDERS to my application).
If I do can you provide part number information?

I am also interested in installing a fuel pressure guage to monitor the Fuel pressure to the injectors. Do you have an adapter for this application, or if I must craft an adapter, what thread is needed to match the fuel pressure guage?

Also, can you give me a feel for the accuracy specifications of your guages?

Thanks in advance for your help!

Your response was much better then the one I recieved, here is what they said to me:

Sir,

You will need to a get t fittings to keep the OEM sender connected for the oil pressure, and a machine shop will have to build it for you. As for the water temp, you would need to drill and tap either the water pump housing or the thermostat housing for the sender to thread into.

I have used 1/8" NPT fittings wrapped with telfon tape and none of them have ever leaked. The 1/8 NPT and the 1/8 BTP (metric) tap that I have are so darn close it is hard to tell the difference. For the temp gauge I drilled and tapped the T-stat housing to 1/4" NPT and put a 1/4 x 1/8 brass bushing in and JB Welded it in place.

[ShawnM]

I have gotten all of the necessary fittings, and adapters that I need, plus a dozen extra just in case I need them when the stores are closed! So Is the t-stat housing about the best place to put the sending unit for the temp gauge, wouldn't being above the thermostat allow the gauge to read the heat only when the t-stat is open? Is there any other places that would be more suitable? What about teeing into the sensor that is under the throttle body? (There are two, one for the trans(auto) and the computer, and the one that is farthest to the left is for the temp gauge in the cluster) Any more opinions? Surely someone must have some on this board!

[ShawnM]

Just in case someone will be doing what I did in the future, you can use a 1/8 tap and tap the threads to fit the NPT fittings. The only (major)difference between BSP and NPT is that BSP thread looks like this /\ and NPT thread looks like this |. Just for your Information.

Here is the answer to the Fuel pressure sender location.

I put my temp sender in the block where the drain plug is...I put a tee in there and still can drain the block....and even have my stock temp gauge. The oil line is also in a tee so I have both them working also. I got all my tees and adapters at Home Depot...and from the local hardware store. Np fit in both my spots with no problem at all...Oil 1/8" and water was 3/8" if I remember,
screwed right in.

[Skyetone]

so whats the final outcome here? I don't run sheit for guages.
I want to add guages. Oil pressure/maybee oil temp, water temp, volt, and a tach. I first think it is laim ass that they don't just give you the friggin adapter. Then I will need the adapter, can I just run to a decent harware store here and get some? Or do I HAVE to go through autometer or summit? I do not want to re tap my block or put faith in a little teflon. My newyears resolution was to slow down and do shit right. we start with my meters.

[ShawnM]

Here is what I did and it works perfect:

Oil Pressure gauge:

- Get a 1/8 th NPT Tap
- Unscrew the stock sending unit
- Run the tap into the block to alter the thread pitch
- Screw in a 1/8th NPT Nipple
- Screw on the Tee Fitting
- Screw in the Original Sending unit (Brass fittings are soft enough that you do not need to tap the fitting)
- Screw in your Sending unit for your gauge

Temp Gauge:

- I just drilled a hole in the t-stat housing and threaded it to fit the sending unit

Volt Gauge:

- Not done yet!

*And use teflon tape or the equivelant on all of the fittings!
Hope that helps!
