I complained to this list about my '75 TR6 coming to an unceremonious halt
after warming up 10 minutes. I would go out the next day and it would start
up fine and repeat the above. Dick Taylor said it sounded like a blocked
fuel filter to him and recommended looking at my fuel filter more closely, I
discovered that my gas tank had become rusted during winter storage in a
damp garage and there was a lot of rust sloshing around in the bottom.

I pulled the tank, and after getting responses from listers on their $200
experiences (one was significantly more) and not wanting to pack it for
shipping etc., decided to proceed with the least costly solution. POR
(www.por15.com) sells their so-called U.S. Standard Fuel Tank Sealer for $30
http://www.por15.com/product.asp?productid=357  , which includes a zinc
phosphate-based metal etching solution, they call Metal Ready. I also had
some of their Marine Clean, but in my view, my tank didn't need it since
there was no varnish or deposits other than rust in the tank.

The application of Metal Ready is crucial to good adhesion, and if you do
MIG welding, you can even use it to coat metal parts with zinc phospate
prior to welding as an alternative to weld-thru primers. I followed their
instructions from the paint can and am now letting it cure for a few days.
It's silver grey, and while not a ceramic coating, I'm sure it will
permanently solve my rust problems .

Finally, for my gas line, and following the recommendation of Randall Young
on the Triumphs list, I bought an $18 25'-foot roll of the Bundyweld 5/16"
steel copper-lined tubing from McMaster-Carr (Part # 5176K24). See
