Reply to "Fuel Tank Sealer or Liner"

I wouldn't do anything to that tank except put a good fuel filter downstream. If you are concerned about the light surface rust and use dilute hydrochloric (muratic) acid make sure you do not seal the tank and do it outside (it offgases chlorine).

As you mentioned, you will need to neutralize with a basic solution afterward. If so you may want to give some thought to using further diluted (with water) acid filling the tank or the normal balm for muratic acid and just reposition the tank several times for coverage. Keep it away from alumininum and zinc parts (ie the vent cap to your tank) as it will dissolve them in short order. Fun to watch aluminum beer cans dissappear. Even funner to make th ebeer disappear before hand

. Undiluted, it will attack your concrete as well. It can be easily disposed of by superdiluting in water.

You will find that it's difficult to keep your tank from oxidizing if it sets long without fuel in it after you use muratic acid.
