Belly Tank Build Diary

I've been around vehicles all my 82 years but never a "side-by-side". Educate me...

Morning Jack, Here is what a "side-by-side" vehicle is.
Hope this helps.

Thanks Tom and Slim. I don't get out enough...

"Index racing"- another form of "bracket racing". I understand its popularity, but can't get enthused about it. My efforts have only been in "heads up" motorsports- pulling and landspeed.

Too bad we didn't have ET clocks in pulling. On good clay tracks my 1,800 pound minipuller ran 300' in under ten seconds- dragging a 14,000 pound transfer sled!

The standard firestop caulk that I used to seal small gaps between my intake piping and the firewall has been problematic.  It gets very hard and is not very compliant.  In addition it is water soluble.  I haul the car on an open trailer and if it rains the smallest amount of water starts dissolving the firestop.  The material cracks up and falls out.  I end up cleaning the material out and reapplying every event.  I found this firestop which is made by Great Stuff and is classified by UL for sealing penetrations.  Has anyone had any experience with this firestop?  Would it be approved for sealing small gaps in firewalls?

The stuff I used is made by 3M and comes in a caulking tube. I forget the exact name but it is commonly available. The stuff looks like red RTV but is rated to a very high temperature and is not water soluble.

Thanks for the heads-up on 3M. I'm also suffering from brittle/flaking firestop material.

Neil is this it? Lowe's has it!

On our lakester we used a fire stop  material that came in a "caulking" tube. Bough at Home Depot.

That's it- I bought mine from Home Depot.

We use this to seal around fire barriers when building hospitals, it is supposed to swell and seal tight when exposed to fire.

Don, I believe that's called intumescent foam.

This is the fire block caulking that I got from Home Depot.  This sealant is gray in color and will crack as it is more like a mortar than what I think of as caulking or sealant.  It is not approved for use as a fire stop on rated construction.  The sealant that Woody references (3M CP 25WB) is rated for fire stop use and is "intumescent foam" as Wayno describes it.  I will try this material and add a post.

A photo of the area that I am having problems with the fire block.  I will clean this up well and try the 3M CP 25WB.

It should work just fine. Smooth it out with your finger and it will look decent.
