Fubar,

Matt's procedure is correct for all earlies except a '64. I just replaced my tank over the weekend, The steps that Matt left out are Remove both wheels, separate metal brake line from rubber brake hose, remove brake hose retainer clip, Remove castle nut and cotter pin from pitman arm, remove pitman arm from drag link, remove bolts mounting idler arm to chassis, Remove front cross member.

The 64 is different from all other earlies in that the 64 has a front sway bay that sits directly under the center of the fuel tank making fuel tank removal impossible with out removal of the front cross member.

Good to know!! Have owned 2 '64's... both had good tanks! Whew!!

On LM's you just rotate the swaybar to get enough room..

Once again it appears I have achieved the impossible.

Removal of crossmember is not necessary. The sway bar if equipped must be removed.

I've done it also on 64s and earliers with the optional sway bar. Never thought to remove the crossmember. That's way too much work.

Thanks for all the suggestions. I looked down the filler tube with the LED camera but could not get it into the tank past a bend in the filler, but I did see was a lot of rust going down. Once I make some room I will put her on the lift, to old to crawl under cars anymore, and really get a look via the sending unit hole.

If there is any rust or accumulated goo in the tank at all do yourself a favor and just get a new one. Cost and effort expended to clean out and seal the existing tank are significant. Any little junk in the tank can get in the fuel lines and cause fuel delivery and more often carb blockages. Some people like to chase crap out of their carbs on a regular basis. I do not.

The cross member may not have to be removed, but to me it seemed easier to remove the cross member, the sway bay comes out with the cross bar, only 10 bolts to remove.

And disconnecting the brake hoses and bleeding the brakes after, and using a separator to separate the pitman arm from the drag link (or using a puller to pull it from the steering box). Removing just the sway bar is much easier as long as the upper link bolts are not rusted up and frozen, but, if they are they need to be changed anyway.

In 50 years when I replace the tank again, maybe I'll look at only removing the sway bar.

It just seemed easier to me to get everything out of the way, the whole job only took me about 7-8 hours working at a leisurely pace.

Actually it would have been less time but my wife kept interrupting every 10 minutes to help her with this or that she was working on in the yard. Wives, you gotta luv them, every time I start working on one of my projects she does one of hers, and hers is higher priority then mine,confused smiley so I must immediately drop what I'm doing and run to assist her. Unfortunately when ever she needs something I'm either laying under the car or up a ladder at the time, no wonder it takes 4 times longer to do something than I originally think.

Count me with those that would rather not remove those rusty crossmember bolts and deal with the cage nuts now with broken bolts in them, and just remove the sway bar! Of course you west coast (and Texas) people with rust free fasteners can do it differently!grinning smiley

Here it is:
1. break bolts holding middle sway bar brackets together.
2. break bolts holding sway bar end brackets on
3. break J hooks holding tank strap in.
4. ....eye popping smiley

It's only about an hour job to remove the sway bar and replace the tank. Only 4 bolts get the sway bar completely off the car.

On my late Model I removed the sway bar and put new rubber on the bar when replacing the gas tank. ALSO, I replaced brake lines with the gas tank out, easy additional jobs to do when gas tank is out.

I had trouble with sealer in Harley tanks back in the day. Perhaps they're better now but I won't go near them. All it takes is some new chemical in the gas to dissolve it. I think Tank Renu is a good thing where they blast before and bake after, it costs about as much as a new tank but is probably better when done.
Just my 2 cents about sealers and I could be wrong, especially with POR-15.

Removing steel brake line connections is scary but I suppose when removing the tank it's the best time to have one go bad.

Before sealing, make sure all the gas is out of the tank.
