Boost gauge question

I got the autometer boost gauge that comes with about 4ft of plastic line. This length wont reach my engine compartment the way I am running it. How did some of you guys route it, and did you have to buy addition line? If so, where did you buy it? Thanks for the help.

I'd say calling up Autometer is your best bet. I know they can provide longer tubing for you if you need it.

I was thinking about that. Thanks for the response. Anyone else have any solutions besides that.

I have my gauge installed in the first AC vent on the right side of the driver. The tubing runs right out a hole in the firewall. I believe the hole is slightly to the right of the engine. The tubing runs from there to the intake. I'll take a look when I get home from work and see exactly where it is.

I have an electronic one now, so the vacuum/boost line is only a foot long, going to a MAP sensor...

But I did have a mechanical gauge at one time and it wouldn't reach the intake. Since I had other things that needed vacuum/boost (MSD 6BTM, superfueller), I just ran a T off the line where it could reach. It wasn't the cleanest solution, but it worked...

You can buy the hard plastic emissions tubing from your local autozone. It generally comes with the rubber ends, but you will only need it on one side. If you don't feel like re-running the line, just splice them in the center somewhere using the rubber ends and a coupler.

Roadie got the easiest solution........................

I bought 1/8" vacuum line Advanced Auto and a pack of 1/8" rubber couplers. Spliced the lines together where the original stopped and in the engine bay I covered them with wire loom. It isn't ugly at all. I think the black loom makes it look very clean. It looks stock if you don't pay attention to where it goes:D .

OK cool. I actually got the rubber tubing from autozone. Another question, can I route it through the hole in the firewall under the PCM and then up to the engine, or is that too much tubing? Will it affect boost readings?

A good rule of thumb is, the less tubing, the better. The longer you run the lines, the more chance you have for leaks, crimps, etc. I try to find the shortest route possible to route any vacuum lines.
