About 20 yrs ago I bought a '67 FB, as a project, an incomplete car a mate found in California. It wasn't much more than a rolling shell.
I stripped it to bare metal, repaired and repainted it as one does. Over time I collected up all the necessary parts and completed the car.
I had thrown away the original fuel tank as it had some light surface rust inside it and treated the car to a brand new shiny one. Maybe a bad idea in hindsight...
I started experiencing problems in recent pre-pandemic times, with the fuel sender unit failing, and I thought some kind of fuel starvation was starting to happen. But then the pandemic arrived so I parked the car up as I had far more pressing matters to deal with.
But recently I decided to finally man-up and pull the tank right out to examine it. First I had to drain off nearly 40 litres of by-then possibly stale fuel to gradually use up in my every-day car. I removed the fuel with a suction pump as the drain plug was locked solid.
Finally I got the tank out, and revelations followed. The fuel pick-up and sender unit was badly corroded, not unexpected. What I hadn't expected was that the entire inside of the tank is also rusty. Flaky rusty. All surfaces both up and down. Yet I'd always kept the tank at the very least half full of fuel. WTF?
The exterior has some kind of galvanized finish with a 'Made in Canada' stamp on the top. But peering into the apertures and looking at the welded seams I can see now that the inside faces have no such coating and from the significant rusting must be just bare steel.
Anyone else had this issue? Time for me to buy a new tank and a good quality one at that. Advice is always much appreciated.
