felixx Posted July 7, 2012 Share Posted July 7, 2012 Vacuum Guage install: Where Am I going wrong? I have Plumbed a T Junction into my vacuum advance line like this: It reads Zero at idle and increases when I put my foot down. Upon thinking this thru this makes sense. Where should I have the guage connected? Regards Glenn Quote Link to comment Share on other sites More sharing options...
Hemi Posted July 7, 2012 Share Posted July 7, 2012 on the inlet manifold me old biscuit, some people reckon there are certain places that are better etc . but tbh and unless your going to be driving and looking at the gauge and doesnt reallly matter . that or if the carb just happens to have a fitting to the manifold after the throttle buttflies that will do too. i generally just drill a hole through the manifold wherever i choose to and run tap a thread with grease on both the drill and tap to minimise alloy getting into inlet manifold/ dont give a fuck Quote Link to comment Share on other sites More sharing options...
kpr Posted July 7, 2012 Share Posted July 7, 2012 yeh^ directly off the inlet manifold would be best. should read close to zero at full throttle. and highest vacuum on overrun Quote Link to comment Share on other sites More sharing options...
felixx Posted July 7, 2012 Author Share Posted July 7, 2012 my inlet is cast iron. I didnt want to drill into it for the exact reasons mentioned. Cast iron filings will be sucky in my motor I shall see if there are any fittings. Regards Glenn Quote Link to comment Share on other sites More sharing options...
felixx Posted July 7, 2012 Author Share Posted July 7, 2012 aha there is a stud, I will remove it and put the adaptor thingy in there, however the stud doesnt want to move, just gave it a spray with CRC, considering it was screwed in in 1967 it will be pretty tight. Cheers. There is tomorrows job. edit: As it is on my carb I dont wanna use lots of heat and striking with hammers. It has a single slot end on it for a screw driver. Any other suggestions (I can only get a stubby screw driver in there and 3 fingers onto the screwdriver handle.) Quote Link to comment Share on other sites More sharing options...
Unclejake Posted July 7, 2012 Share Posted July 7, 2012 Any other suggestions? The obvious one is to chuck away the vacuum gauge brother. All it will do is fixate you and tear your attention away from the road and family life whilst you angst over why the vacuum at 67.3 kmph was only 13.2 inches of mercury when the manual says it should be more..... etc.Vacuum gauges came out standard in 4 cylinder Commodores and that's about it.......... and although 4 cylinder Commodores had an interesting place in post energy crisis NZ motoring, they were still spack. Spack as a cheese fondu, Timeshare apartments and de-ionizers. Spack Quote Link to comment Share on other sites More sharing options...
Spencer Posted July 7, 2012 Share Posted July 7, 2012 Yea man its only a good tool for tuning a gimick for every day. Also the vacuum advance port is meant to give no vacuum at idle even though the car is pulling max vacuum then. Stops the vacumm advance being dialed in at idle, the port for this usually setup so the throttle plate blocks it off at idle. There is huge debate about if you should have the vacuum advance coming in at idle but we wont get into that. I think I said idle to much Quote Link to comment Share on other sites More sharing options...

UTERUS Posted July 7, 2012 Share Posted July 7, 2012 Disregard that, mash it into the passenger side to give glenn jr something to look at. Quote Link to comment Share on other sites More sharing options...
kpr Posted July 7, 2012 Share Posted July 7, 2012 only if it says something sweet like "power" & "cruising" on it Quote Link to comment Share on other sites More sharing options...
felixx Posted July 7, 2012 Author Share Posted July 7, 2012 It does have cruising and power on it. It is only a wee 2" gauge. Since the anglia doesnt go very fast a twitchy little gauge will give passengers something to look at because the view doeasnt change thru their window much..

BlownCorona Posted July 7, 2012 Share Posted July 7, 2012 this will explain why vacuum gauges are great, and a few posts in this thread are wrong. good cheap problem diagnosis, none of this tuning stuff, use your ears for that.. http://www.secondchancegarage.com/public/186.cfm Quote Link to comment Share on other sites More sharing options...

If you can tune my car for max vacuum at idle by ear you are gifted Quote Link to comment Share on other sites More sharing options...
Bling Posted July 8, 2012 Share Posted July 8, 2012 It's your car Mr Felixx, I wouldn't worry about all the haters. It's not like you have a fake oil cooler or fake rims on the car. Go nuts I reckon, I have one too that I intend to sit low spec under the dash if I ever get my escort on the road. Purely for interest / lols / cos I can. Good luck working out the best place for the feed. Quote Link to comment Share on other sites More sharing options...
felixx Posted July 8, 2012 Author Share Posted July 8, 2012 Cheers, there is a stud, but it is on the rocker cover side of the inlet mani Even after removing the rocker cover I cannot get at it easily. I will try removing the carb and see if thet will allow me to get at it. If it had a bolt head on it, it would be great, but it doesnt, only a single slot for a screw driver. (If I remove the carb I can get a set of vice grips onto it) Quote Link to comment Share on other sites More sharing options...
Bling Posted July 8, 2012 Share Posted July 8, 2012 If it's steel I could probably weld a nut on for ya in Hornby. Vice grips probably a quicker solution though given travel. Quote Link to comment Share on other sites More sharing options...

Unclejake Posted July 8, 2012 Share Posted July 8, 2012 If you put the gauge on the passenger's side then watch out for the glass breaking, coz if it does that 105E suction will pretty much implode the car and suck your teeth out and down the pipe/not really WRT the thing you were trying to undo from the manifold: I have a vague recollection of a screw head being part of the early manifold castings. I could be confused with something else on another motor, but just be certain that you are seeing a removable thing and not part of the factory casting (you will know of course as you are looking at it). I doubt you are going to get a significantly different result from moving the pipe though........... have you check that the diaphragm in your dizzy is intact? Yeah, and don't pay attention to any of these likers. They are just un-jealous. Quote Link to comment Share on other sites More sharing options...
felixx Posted July 8, 2012 Author Share Posted July 8, 2012 Hi UJ> It was a stude, it did unscrew. Now it has been removed. I installed the guage just to see what happens with the engine (I am a curious george) Then I will probably take it out and just use for tuning times. Cheers for all the advice guys.
