In the last few years I have seen several people use a gas tank liner coating. I just can't remember who, hopefully some of you will speak up and tell me what product you used and how it performed.
I haven't driven "Miss Smokey" in about 2 years and fought rust in the gas tanks the 5 years I drove her. I have a friend with an automotive shop and a radiator shop, he is going to clean the tanks for me. With the ethanol issues it seems like a good idea to line the tanks and redo all the lines (overdue anyway).
I am open to all suggestions on best practice in regards to ethanol and any other issues.
I will make sure I don't have clearance issues with the lines, and will probably simplify things by doing away with the canisters and separator (leaks anyway). I will probably improve the venting system also. I haven't kept up, I am wondering if there hoses that have more resistance to ethanol damage or if that is a concern for "ordinary" rubber gas lines?
If I get time I will make pictures of the tow rig and post them. I am sure it was a site to see, a Grand Cherokee towing a 26 ft GMC. I have a U-Hall bumper hitch that worked flawlessly ( Bob, I don't guess you all rent them any more, do you?). I only drove about 20 MPH but I think 30 or more would have been ok had I not been in low range.
Thanks

Marsh,
I purchased mine from Kanter Auto Products (Boonton, NJ) which is the parent
company of Packard Industries. I have used it in four cars to date, two
1956 Tbirds a 1961 Jaguar and a 1969 MGC. I only mention the years to give
you an idea of the condition of the tanks. All cars were in New Jersey at
the time. So they were subject to rust, condensation etc. The main thing
to ask - at least when I did it - was is the coating impervious to today's
gasoline. Some of the early liquid coatings flaked off or dissolved over
time gumming up the fuel system.
I drained the tanks and put two different types of chains and a handful of
assorted nuts and bolts in the tank. I added a quart of rubbing alcohol and
sloshed this concoction around for a while. Count all the pieces so you are
sure you get them all out. All the different geometric shapes helped to
loosen the junk and crude from the tank. And a lot of stuff comes out.
Repeat if you want to. Then I rinsed it with more alcohol. Allow it to
dry and then slosh the sealer/treatment around.

Marsh,
When you do re-do the lines DON'T connect the two vent lines that run up to
the filler neck at the tanks, run TWO SEPARATE lines up as close to the
filler neck as possible then connect them to the Tee! This will reduce
burping problems when filling.

Be aware that GMC tanks have two baffles in them that will interfere with the chains. I tried washers, nuts, bolts and all kinds of stuff to get the rust out. With all the bumps, channels and stiffeners formed in the tanks the hardware was just not able to scrape all the rust off. I'm still trying to get the hardware out. I gave up on that method and pulled a tank from my spare parts transmode and sent it out for chemical cleaning. I used the POR-15 material to coat the tank interiors. Since I don't have the GMC on the road yet I don't have any comments on how that coating works.

Good point Steve, The Jag tanks consisted of two - 9 gallon tanks with no
baffles. The MGC tank did have baffles and I only used hardware in that
tank.
