Just thought I would share a recent experience that may helpothers. I installed a Pingelpetcock and found grey flakes around the petcock filter. After investigating further and from an Internetsearch apparently during some periods HD sealed the fuel tanks. My bike is a 1995 and there was a grey linerin the tank and it was flaking. Itappears the ethanol fuel may be the issue. Not sure of the facts, but I was fortunate to find just before a longtrip.

 

What did you do to fix it?

 

Still in the process of cleaning and sealing. Used a small chain about the size used on a porch swing. I read a post in a forum where a guy used a large chain and when he shook the tank it dented from the inside out.

So I shook the chain to loosen the sealant and also scraped where possible with a long screw driver to loosen where bubbling. Next step was high air pressure. It appears most of the sealant is out.

I ordered a kit from J&P and this is the link from the manufacturer.

I had a piece of grey liner about the size of a USA quarter release on a 1998 Road King (fuel injected).
The grey liner piece was right next to a bracket within the tank.
It would get sucked towards the filter sock and starve the bike of fuel.
Released throttle, coasted and the piece would float away to return again a few minutes later when it blocked the filter sock.
It was rather easy to spot once home and the access panel was removed.
In my case i was able to locate, remove the USA quarter size piece and filter the fuel through a coffee filter.
No other part/liner piece was loose.
I would imagine that age and ethanol were involved.
The fuel injected fuel lines developed a leak about the same time.
All good for several years now.

 

My '94 has a yellow liner, and it's held up well.

When I cleaned the sediment out of it a few years back, I used a piece of brass chain I bought at the hardware store. It was heavy enough to knock the sediment loose, but not heavy enough to damage the tank. I went with brass as it's non-sparking-the service manual cautions you NOT to use steel ***** or chain for this reason.

I went with a piece of chain instead of lead shot because it's easier to get back out of the tank afterward.

 

You could pour in a gallon of acetone in the tank, seal it up and agitate it now and then. It'll melt the liner and in about 48 hours you can our it all right out. Just don't get it on your paint if you plan on keeping it.

 

I've never heard of that tank sealer.
Have you used it before?
Does it work better than POR-15 or Caswell?

 

I agree, if you want to be done with it, use a 2 - part epoxy like the stuff texashillcountry mentioned from caswell. Of course after proper prep of the tank....

The one part stuff is no good. Remember Kreem? That stuff was a nightmare! Long term, the only thing I know that holds up to todays fuels is the 2 part epoxies.

I have no experience with the por 15 product. YD

 

It was supposed to be top of the line before Caswell.
It isn't as thick as Caswell so it flows better but I have heard good and bad results with it.
I suspect the bad results were because of improper tank prep.

 

Good advice on the chain, guess I did not shake it too hard and am here to type.
