    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Removing old gas residue

Im rehabbing the 78 1000C to sell it. Someone here once posted about what chemicals to use in a tank that has a POR 15 liner in it. Just want to rinse it out good to get any gummy sludge that may be in the bottom out. I was thinking maybe Acetone but unsure if that would harm the liner or not. I will be removing the fuel sender unit prior to cleaning.
So post up your favorites and a little tutorial on your process., Thanks.
 
I was thinking dump the gallon of berrymans in and shake it now and then. Thought about that after i posted the thread.

No way. That crap is harsh and will eat the liner. NO NO NO.

Even the new stuff will strip paint. I have a gallon can that has taken everything I've thrown at it. It will be a small superfund site someday.

I would use Dollar Store's yellow 'LA's Awesome Degreaser', which is amazing stuff. 50/50 with water or straight up. I have never found a better degreaser for the price, and I'm pretty sure it would work. I'd put some BB's in with it, the sauce to agitate but not go crazy. Just to scuff up the surface of the scum a bit.

Goof Off is a powerful cutter but doesn't harm painted surfaces. Goo Gone is citrus-based; I prefer Goof Off. But maybe Goo Gone would suit this task. Both of those are too expensive, though, so throw a $1.25 bottle of LA's (if you can find it where you are) at it, I'd say.

Start with mineral spirits. It's pretty benign, it's a cleaner version of kerosene and will dry clean to the touch. It should dissolve old gas residue and not effect liner or paint.
 
Was reading seafoam will break down any varnish. Dumped a can in and will periodically shake it around. We shall see.
