Did a complete body-off restoration of Model A 25 years ago. Cleaned gas tank at that time, but did not use sealer. Last summer went to a Weber carb set-up (very happy).

Problem is I have had to change fuel filter several time since then (rust crap build-up). Before I installed Weber I cleaned the tank with detergent and water, then flushed twice with acetone (lots of crap came out). Used hair dryer and then vacuumed out as best I could. Let sit for a few days to fully dry. Yes, the acetone destroyed the ‘float’.

Months on I have had to change the fuel filter several times as rust trash builds up. I went back to using the glass bowl before the fuel filter, but without a gas pump it slows the fuel flow down to slow.

Here is the question: I want to clean the tank again, but I do not want to take the gas tank out of the car.

I have seen several videos on YouTube concerning what to use:

Metal Rescue, Muriatic acid, vinegar, Oxy Clean, and ‘The Works Basic’ (a toilet bowl cleaner). From the videos The Works Basic seems to do the best job.

ANY suggestions/ opinions from experience?
