Having sealed a tank with the POR15 Frost kit I can tell you that it's amazing what crud their "Marine Clean" cleaner will shift, and also that you REALLY need to remove the gauze filter. I didn't. I now have a different tank.

 

Sorry missed this comment; I agree that filter has to come out if the tank is to be painted inside.  However if I could get the filter out I would be able to fix my tank.  It’s on the end of a length of steel pipe that would have to be bent to the fuel sender hole.  Last resort action before I start looking for a replacement tank which appear to be readily available.

There is no non-return valve in the fuel outlet.

 

When my tank outlet was blocked I also used full airline pressure and nothing came through.

 

Ended up using another tank.

Neglected fuel tank summary:

 

·         The tank was not rusty inside but was coved inside with black crystalline deposits.  These deposits jet washed off/out.

 

·         The tank outlet pipe is fitted with a non-replaceable strainer that probably makes it difficult to use gravel in the tank to remove rust.  It also probably means that, unless the strainer can be bagged and sealed, tank paint is not a good idea either.

 

·         Tar builds up in the strainer and outlet pipe, if the car is stood for some time, and is difficult to remove.  It can be done with wire and Acetone but blowing compressed air up the pipe just forces tar into the strainer and makes matters worse.

 

·         I managed to get Acetone flowing in but still no petrol flowing out.

 

Replacement tank picked up off eBay.
