Autometer boost gauge, came with hard plastic tube..should i use this or vaccum tubin

[koreanpersuasio]

Hi. This gauge is weird. It came with this hard plastic tubing. I spoke with autometer..and they said the supplied tubing was 1/8...but its smaller than that..i think its closer to 1/16. its hard plastic..and thats the only one that will actually connect to the back of the gauge. Now i bought 1/8 vacuum tubing...should i use this instead?

No, I used that tubing, I just clamped another hose around it!

It's your call. I used some of the silicone hose from my Hose Techniques kit. Easy to run. That plastic tubing can kink if you're not careful. Plus it's just harder to run it. I'd go with silicone vacuum hose instead. My .02 cents.

yeah, I kinda have been having problems with my autometer. When the gauge is in vacuum... it's sticky. It never really shows any vacuum unless I tap the gauge while I'm coasting.
The hose is free from kinks/obstructions as far as I can see.

Also, I got frustrated trying to find a place to run the tube into the engine bay, so I poked a hole through the steering boot through the firewall on both sides, and just ran it through there, heh.

I don't think this would be the problem, but any input?

 

[koreanpersuasio]

did you use that hard plastic tubing that came with it? or did u use vacuum tubing?

use the plastic line with the automerter gauge. it will not kink or collapse when pushing it threw the steering wheel boot, or in any other place where pressure is placed on the line between the vac source and the gauge. all i did was run the plastic tubing all the way to where i chose to tap for the vac/boost reading. which was at the intake manifold. cut the rubber vac hose and stuck the plastic hose into the rubber hose. it will not leak, and you will have a hard time pulling it back out if you need to. so make sure you cut every thing to lenth right the first time

 

[koreanpersuasio]

Ok. I wasnt sure if i should use the plastic tubing or vacuum tubing. It was confusing to me

 

[jdmawd]

just leave a little rubber vac hose on the engine side where you tap for the boost signal. so you can push the plastic tubing into it. i had this setup on the mustang for 3 years and it never leaked, and read vac/boost perfectly.

Thanks

I had to mount my BCS (GReddy Profec-B) in the cockpit so since I already had tubing coming through (under the battery where there is a hole and cover already made in the firewall) I just tee'd it off that. One thing I figure is I know EXACTLY what my boost controller is reading.

i ran the hard plastic tubing into a length of rubber hosed, tee'd under the hood. so far had no problems.

 

[koreanpersuasio]

thats what i did too. i ran it to the fuel pressure regulator..and rite before the tee..i used 1/8 tubin...and ran the plastic tube into that..then the vacuum tubin into the tee. works perfect

I used the plastic hose that came with it and i havent had any problems yet.

 

[koreanpersuasio]

Yep, it works fine. thanks!
