Gents,
I have beaucoup problems with my fuel tank. Though I don't have any rust per se, it seems to have "issues" as we say. Some of our dear friends JA17 Joe Alexander and Dr. Benz Dan Caron are well aware of my problems.
What happens with me is that as my tank gets down to close to 1/2 tank, it seems to "suck some air". Gernold seems to think that my fuel pickup line inside might have holes in it. Tim Kidder at K&K in Sparta Michigan agrees. (n.b. K&K is a sheet metal supplier for MB cars)
One curious item is that there is a neat welded patch on my fuel tank; sometime in the past 35 years, SOMEONE was inside. Whether or not this has anything to do with my problems is anyone's guess, but sometimes the diagnosis is more costly then the cure.
Good News: K&K has had new 280SL style fuel tanks manufactured in Eastern Europe, and on his next import container the first load is on them. Next spring I'll pick one up. I don't think he's set the price yet but you can be sure it'll be less then the MB price.
