Title: Out with the old, in with the new
Post by: Chanman09 on February 21, 2023, 05:16:58 PM
Spent the long weekend getting the new tank and sending unit ready to install.  Took off the bolts to the bed in order to raise it and only had to cut one nut off and ruined one bolt in the process.  I have the new carriage bolt and nut on the way and will probably get this little project marked off the list soon.

Curious as to how the foam strips will last. GM used heavy weight tar paper. When I redid mine I just cut strips of #40 asphalt felt paper to match the factory. When you buy the replacement stuff it is essentially the same, though it may be a bit lighter weight.

Will last until you remove the tanks again.

I’m curious too. It’s pretty heavy rubber type stuff. Not what I would call foam necessarily. I used it on a previous project a couple years ago. It’s held up nicely for that use.

I may be regretting it. We’ll see. I still have time to replace it before the tank is in, as I reached a stopping point before I put the tank in.

I hope so. It’s lasted very well in a previous project. But not nearly as old as this truck.

The only thing I could see is that the two strips create an area for road grime to potentially accumulate between them. Depending on the type of foam tape, if it holds water and stays wet it can create a poultice corrosion. Probably pretty hard for road grime to get into the ends of the straps as they are wrapped around the tank, but it seems to find every little nook and cranny that could hold grime. Just thinking out loud. If you have done it before and are happy with it, great!
