Subject: Re: Rust Inside Propane Tank
Content-Type: text/plain; charset="iso-8859-1"
When I replaced valves and sand blasted and powder coated my propane tank I
did not even think of looking inside. I wish I had. I do know that Naval
Jelly does a great job of getting rid of rust. Or maybe that CLR kitchen
stuff (Calcium, Lime & Rust remover.) Perhaps a bottle or two or three
dumped in your tank and shaken up a bit to spread it around and then
flushing it out with water a few times might do the trick. The challenge is
how to dry it out. Compressed air? Heat gun & vacuum cleaner?
I'd love to know how you solve this problem. I'm sure I do not know, but
maybe someone else does.
These vanagon challenges get curiouser and curiouser. For me, however, when
it comes to safety with gas new is much less costly than a serious down the
road problem.
The previous owner of my vanagon had to replace the gas tank (and the fuel
injectors twice) due to rust in the gas lines and the tank. Solving that
expensive problem before I bought the van was good for me but I know the PO
must have thought the van to be a money pit.
