Recently, I had an aluminum gas tank from ebay delivered to replace a client's rusted out one. The construction looks good(haven't tested it for leaks yet) and the sending unit(of unknown origin now) is located on the top and reads 0-180 ohms--good. Sounds nice until you find they put the sending unit RIGHT IN THE PATH OF THE LEFT METAL HOLD-DOWN STRAP???
I have sent a message to the seller(England? ) but hope he will correct this problem.
BEWARE

Notice the 2nd pic where the positive lead for the sending unit is. A double layer of old bicycle tubing as well as a 3/8" hose eas needed to protect it from grounding out from the hold down strap.
The 3rd pic shows only 2 breather tubes for the tank, so the breather for the axle is now left off. There is no pressure relief valve as on the original tank.
Finally, here's a correct sending unit box/number since the one they sent was backwards (and only 180 ohms).
My advice would be to get the one from Martin Robey, as it shows the correct fittings.

I bought a new fuel tank from Martin Robey this past summer. It arrived three days after ordering it. It was well packaged without any damage. It is a quality made part and installed without any modifications. It was definitely worth the premium to get the right part.

In the past, I sent the tank of my Austin Healey to an outfit that advertised a substance(?) to slosh around the inside of the tank,
sealing up holes . After reinstalling back into the car, I was especially
watchful for leaks that never materialized.

I will admit, I never had the confidence that a NEW TANK could offer,
but by the same token , the SLOSH METHOD never leaked.

Sander's fix with POR15 has been the "standard" for a long time, but some tanks(2 recently) have been "worked/fixed" by another method so they are no longer repairable without an inordinate amount of extra time, thus making a replacement one a cheaper alternative, especially if it's aluminum or some other non-rusting material.

Sadly, aluminum is not resistant to corrosion. It is very susceptible to salt and water, but instead of turning into red, crumbly corn flakes, it turns to white powder.
It is the water in gasoline that rots fuel tanks, and aluminum will likewise suffer if the fuel contains water. I suppose it will last a bit longer that steel under the same conditions, but after 50 years who knows?
Aluminum blocks and heads will get severely corroded if the coolant is not replaced regularly, since the corrosion inhibitors are depleted over time.
Just something to be aware of. Maintenance is still needed, even if a component is made of aluminum.

Aluminum fuel tanks are common in boating which is a much harsher environment than anything ashore. Some things I've learned over the years about maintaining aluminum fuel tanks. Keep the tank topped up it reduces air space for condensation which is where water in the tank comes from. Run your fuel tank as close to empty as you dare whenever possible, fresh gas is good gas. You can also treat gas with a water absorber which disperses the water and allows it to burn harmlessly through the system with the gas.

I recommend Moyer Fuel Tank Renu in Greensburg, PA tank.com" TARGET="_blank">http://www.gas-tank.com , their work is excellent. All rust is cut out, not covered over, it's completely rebuilt as needed and no fuel tank is too far gone for them to repair. The tank will never rust again. They did my tank years ago and it was in the $400+ range, but every tank is different on the level of work it needs.
