2002 F-250 SD XLT V10

While rummaging in my garage a couple of days ago I stumbled upon a vintage Stewart Warner mechanical vacuum gauge. I would like to install it on my truck.

My question is: Where is a a good connection point for the vacuum line? Detailed direction/photo preferred as I am both Ford and V10 engine challenged.

Same question with respect to following gauges:
Volt
Oil Press
Water Temp

Thanks in advance!

 

I don't really know why you would want to hook up a vaccum gauge at all maybe you like the little fuel economy gauge in uhaul trucks but using mechanical gauges in newer vehicles pretty silly when the pcm already monitors most of what you want to see anyway you just need an obdii gauge that reads live data like the scangauge ii edge cts and the sct livewire if you were ever thinking of getting a tuner there are also smart phone apps you can use with and obd adapter. Unfortunately the pcm does not monitor oil pressure or temp or vaccum or fuel pressure but none of those are really necessary to monitor in the v10 anyway. You will be able to see coolant temp trans temp, and volts those are really the only things worth looking at. My 4th gauge on the scangauge lately has been intake air temp since I don't have a outside temp display being an xlt. You can see a probably about other things as well but none that are super important to monitor all the time. That all being said if you really want a vacuum gauge pick a vac line and t into it the easiest one would probably be the brake booster hose but it wouldn't be my pick. There should be a vaccum diagram under the hood btw.

 

Why would I want to hook up a vacuum gauge? How about because I have it, because I can and because I would like to monitor engine vacuum.

I do have an UltraGauge. Per the web site it measures 78 different functions (UltraGauge OBDII Supported Standardized Gauges). Amazingly, not 1 of the 78 is engine vacuum.

When trouble shooting fuel delivery problems the diagnostic tree says to check for vacuum leaks.

Well, a mechanical vacuum gauge would do just that.

You reference "smartphone apps." As this may come as a shock to you, perhaps you may want to sit down? Not everyone in the universe has a smartphone. I am one such individual, I say unashamedly.

I come from a point in time when motor vehicle engines had carburetors, distributors, ignition points, etc. Can you say 'old school?" If you want to classify me as old fashioned, an ol' codger or an old fuddy duddy that is ok. I can handle it.

Even though I am old school, in these modern times of today engine vacuum, battery volts and engine oil pressure are still relevant measurements. Those gauges, along with an engine hour meter, would furnish instant readings without having to troll through the 78 offerings of my UltraGauge; which is both time consuming and dangerous if undertaken while driving.

Mike, I trust I have answered your question as to why. I also hope you are not offended by my answer. I do not want to offend and was not offended by your asking "why you would want to hook up a vacuum gauge at all" or your statement that my "using mechanical gauges in newer vehicles [is] pretty silly."

 

You sure have and while I get it and was genuinely interested as to why and for trouble shooting it would come in handy like you say I still don't see a reason to monitor vaccum all the time if you want too and have the gauge which you obviously do so go for it. Your ultra gauge doesn't monitor vacuum because there is no sensor for it just like it will not report some of those 78 other things since there isn't a sensor for the pcm to see it can't report what it can't see just because the ultra gauge can monitor it doesn't mean ford but a sensor there. As to your comment about smartphones I never told you to buy one I just suggested it as an option to read live data as most people do have one young or old just like I did the other things I listed prior to the apps which most people actually don't have I don't care if you have a smart phone or not and there was no reason for your little spiel about it. Luckily I was sitting down but thank you for the warning as I got a bit faint when I learned that not everyone has or wants a smartphone. What I meant to say about mechanical gauges was it's pretty silly to hook up one for something that the pcm is already monitoring with a sensor that's already there is silly which 2 of the 3 (water temp and volts) you asked about are being monitored by the pcm in my opinion of course and you know what they say about opinions. Maybe since I typed it on my smartphone it wasn't as clear as I meant for it to be. Anyway enjoy your vaccum gauge.

 

Mike,

Well, it is heartening to know that we both are able to "reach across generations" without alienating one another. I appreciate and respect your viewpoints, but that is not to say I wholeheartedly agree with them.
