new gas tank

[gmcdeadhead]

im in the process of putting a new carpet in the 66 c-20, i am also going to replace the in cab gas tank, i had a new one for a couple of years now and now going to install it soon , should i coat the inside with the tank cream or just install it as is?

How long did the original gas tank last?

the original gas tank was replaced in 1983, since i have everything out in the cab now and had a brand new one sitting in the garage for the last 4 years , i was just gonnna replace it with all the other gas tank parts

I don't know how old you are but in my case I'm doubting I would be around when that tank needs to be replaced again.

it only makes sense to replace it now while i can get to it easy and i have a new one laying around . the truck smelled like gas every time i filled up so i no the rubber was dry rotting. but would you guys use the tank cream or no?

No.
I would make sure your sender gasket is new and correct as well as the supply tube. So as to eliminate the gas smell.
If there were even a chance of that stuff peeling, which there is I would not use it.
I say this because my tank on my old 32 had some peeling when it was installed, floats to the filler tube bla - bla - bla
