Replace soon or no?

I would replace it. Thery are not very expensive, I replaced one on my old trailer, think it was around $150

 

Replace, and rehab old one as a spare, sandblast, paint

 

When you are about to start your home time, depressurized the system and give it a whack of the hammer.

 

If you are asking, u already know the answer

 

Yeah @Jonjon499 those tanks aren't very expensive....im talking maybe like 2-300$ and its something you can replace yourself.

 

Practically a new tank on a Ontario trailer lol

 

John i have 2 laying in my garage
Mint ones from 579 tool boxes

 

I wonder if the insides rusty? I’ve had gas tanks look like new on outside, rusty inside. Rusty outside, like new inside. Usually one or the other. Same with body panels, especially doors.

 

Use a needle scaler to remove paint and rust. Yours looks like a little rust under the paint. Or as mentioned earlier, whack it with a hammer.
