I asked the same question in my post "rebuild or not". Has anybody tried use one of these fuel tank polymer lining kits on their rusty fuel tank. If it doesn't work on the 124 tank then I'm looking for a good deal on a new tank. Any suggestions?

I used one of those kits that clean the tank, prime it, then coats it. It seemed to do the job. I've heard of others using these kits. My car is apart so I haven't got to try it yet. I can't remember the name of the kit. I think Eastwood sells a kit. The kit I used was cheaper than theirs. Check around, there are different ones out there. The only thing that is hard is they say not to leave the final coating sit in the tank and build up in one spot. As your turning the tank, the stuff doesn't want to come out. So you have to keep turning to distribute the stuff.

In restoring my 76 spider I had to clean out and coat the fuel tank. I bought 2 kits from a local motorcycle shop. It takes two of them to coat the tank. It cost me about $90 and worked great!

the fuel tanks have baffles in there. hard to see how a liner would work with all that in the way.

It's a liquid liner. Just have to keep turning the tank to coat everything.

i removed my tank and took it to a radiator shop, they cut the lower half out, removed all the rust, welded a new metal bottom onto it and then coated the inside with some type of epoxy. Cost me less than $100.

I used a liquid liner called KREEM, it worked fine, but takes a little labor to get all the rust out. If a radiator shop will do it for under 100 bucks, that sounds like a good plan. The liner In bought was only about 40 bucks though from JCwhitney.com

I used a liquid epoxy type liner on my porsche tank and as mentioned, gotta keep turning that tank in order for it go everywhere. This "glue" filled all pinholes and I'm still using that tank

Hi Charles,
I have just seen your posting and will put in my 2 cents worth.

I see your car is listed as a 1981 so I assume is fuel injected ? If so, i suspect that any tank sloshing / sealing compound will severly clog up your fixed fuel pickup. If you have a carby car, the pick-up will be thru the sender unit and therefore not a problem.
If you need to replace the tank, remember that a 124 Coupe or 124 stationwagon use the same tank, as does the Lada (Vaz) stationwagon (2105 ?? )so they may offer a source for a usable salvaged unit ? I put one in mine and it worked fine. I just had to solder in a new pick-up. EFI pumps are set up to PUSH the fuel, not SUCK it so need to pick-up from lower level !

I just put a bunch of gravel in my tank and shook it for an hour or two, then flushed it out over and over, painted it and reinstalled it. Didn't even know these epoxy coatings existed until after I had it back in the car and my cousin said "what you should have done is..." Oh well, I can buy about 20 fuel filters before I get to the $100 mark. Should have signed up with this forum back in the 80s when I had my first spider. Imagine the knowledge I would have gained over the years!

I've stopped using Kreem and started using electrolysis on old motorcycle tanks... It won't fill holes, but it is a lot easier than the Kreem kits, and very effective.

On the outside of the tank, but you can build the 'rig' using the tank as the 'bucket':
