I'm installing a boost gauge from Glowshift and wanted to use the port on the side of the 98 24V engine to get the boost pressure. They supplied some plastic tubing with the gauge but it seems to me that installing that tubing on the side of the engine would cause the tubing to melt from heat.

Right or wrong? What tubing could be used instead - short of brass tubing. That would be a pain to install.

You need to get a 24V Boost bolt or drill and tap the intake horn. Nylon line or air brake line works for tens of thousands of members here - Im pretty sure it will work for you as well.

A tapped airhorn can be seen in this pic (although it is difficult to see):




Besides, where exactly would you get this brass tubing your talking about? I suspect your thinking of copper tubing and its no good due to the high vibration these engines create.

I drilled and tapped the intake horn for 1/8" NPT, then ran a 1/8" nylon tubing into the cab. Zero problems.

And this is the boost bolt I was talking about:

Here's the one I usually get.

Clicky.

Thanks for all the replies about the boost guage install. If I drill an tap the intake horn, what about the shavings? Should the horn be taken loose first and then drilled or can I drill an tap while it is connected? Sorry to sound stupid but I don't want to mess up anything with shavings.

Saw you had your gauges installed in the column. How did you ge the fit so good? Working on that with the gauge install.

In the column? Not me.

I do have three on the pillar and one in the abandoned cubby hole though.

Pull the intake horn and do it on the bench.. Only takes about 5 minutes to pop it off.

A little off subject but I have the glowshift boost gauge and the lip on the back of the boost gauge isn't big enough and it tends to pop the boost line off the back of the gauge above 30psi. It seems to be a common problem with them, I fixed mine by putting a zip tie on it, it's good now

The glowshifts have a barbed fitting? Yikes.. The Autometers and Isspros uses compression fittings on hard tubing. Required for any significant pressures IMHO.

I took the horn off to drill and tap. Definitely not the place to have shavings fall in, and all it takes is 4 easily accessible bolts. Used 21/64" drill and 1/8" NPT tap. Standard tap works fine, no need for bottoming tap on this one.
