Engine guage connections fo a F-134

I'm just finishing up my 67 :hurrican: equipped ECJ5 resto. I started the :hurrican: the other day and I found myself wondering about what the oil pressure was doing.

I decided I would like to install a temp and oil pressure guage in one of those pods on the bottom of the dash. Where have some of you who have done this on a :hurrican: connected the sender units to the :hurrican: ? I'm planning on using all mechical guages.

Thanks!

 

I simply replaced the existing senders to the cluster with the mechanical senders to the gauges. Oil sending unit location is on the drivers side near the back of the motor down low, below the throttle pedal linkage and behind the ross column. Temp sending unit location is on the passenger side up high on the cylinder head. I believe my cheap SunPro temp gauge came with the necessary adapters. Be sure to get some teflon tape for the temp sending unit install.

 

Hello, I would like to offer a little advice on the oil pressure gauge. I would not reccomend the plastic oil pressure line, it tends to get brittle after time and is very prone to break, especially in very cold weather. I use copper tubing. Some gauges come with the plastic tubing and some with copper and some with none. Just a thought, good luck.

Good advice on the plastic tubing. I've had that in a 78 CJ for about 12 years now with no leaks, however I have always wondered about it. I'm planning on keeping the Factory senders if I can. At very least the Temp sender. I noticed what appears to be a threaded water jacket plug just to the drivers side of the thermotstat housing on the head.

 

Copper v. nylon is a religous debate which (I believe) is well documented in the archives. Suffice to say some people think one is better than the other and some people like the other better than the one.

Here's one for ya! I used the original sending unit location, put in a tee, kept the idiot light and added a gauge with plastic tubing (although copper would have probably done me as bad). Scenario: I placed the tee facing "out", 1 line up, 1 line straight out. Bad idea. Out goofing off near home, climbing a fairly steep hill, spun out, hit reverse and started to use brakes to come back to a better spot. Guess it had been a while since I added fluid; a steep hill left me with a low reservoir, pedal went straight to the floor, cleanly snapping the plastic tubing off on the way. Mostly brakeless, though not in trouble I was looking for a better route when I smelled bad smell troubles, like really hot oil. Good thing I was close to the house! Changed that setup that night! Moral? Whatever you do with an oil line down there, just make sure a dead pedal doesn't leave you up the creek.

 

If you look on the side of the engine, we'll call it the left side, because that's what jeep called it---but it is the side with the exhaust manifold.

you'll see several 1/4 inch plugs screwed into the side of the block at an angle. These are all taps for the oil gallery -- that's were the pressure is measured.

So if you want to have both the idiot light and a gauge, simply remove one of the plugs and insert the fittings and line for the mechanical gauge.

You could put in a tee on the sender if you want, but any of the unused taps will work as well.

Here's a technical tip---- when buying the fitting to screw into the block, also buy a plug or male fitting that will screw into the female end of the fitting. install the plug or male fitting into the fitting you are going to install into the block first. Remove the plug once the fitting is installed in the block.

Why? It prevents the female end of the fitting you are installing from getting deformed when you are putting a wrench to it. Nothing worse than putting the fitting in the gallery hole and finding that you have to remove it because it was bent in the installation process.

The other tech tip is when removing the plug in the oil gallery, be gentle.
If one seems as if it doesn't want to budge, try another.

I'd also avoid the plug that has the spring for the throttle attached and leave that one alone. You've got others to choose from.

For the temp gauge there is a plug on the water pump. You could tap in there. Or you could install a tee where the current sender is. I've never done that (had both gauge and calibrated gauge at the same time), but I don't see why not.
