Durwood ;
1st & foremost : DO NOT use Muriatic acid ! IT EATS GOOD METAL !
anyone says otherwise doesn't know what they're talking about ,
_PERIOD_ .
Phosphoric acid doesn't eat good metal , only rust ` it _CANNOT_
damage your irreplaceable Suburban tank .
If you're still worried , look in 'phone book for " Gas Tank Re-Nu "
it's a chain that uses a system to repair any tank , even totally
rusted out ones and they'll gaurantee it too .
$pendy to say the least .
I'd do the Phosphoric Acid thing but no good clothes and not on the
lawn nor on nice cement as it'll etch the shiny cement driveway and
kill the lawn .
_After_ it's de-rusted , you can either have the hole welded or use
POR-15's gas tank kit to fix and line it , use tape on the outside
of the hole as a dam untill the lining sets up and NO SHORTCUTS !
this is why some folks claim the tank cleaning and lining kits
don't work = they skip steps or say " that's good enough " and it
never is ~ take your time , do not rush any part of the job .
I use Phosphoric Acid and packages of BBs to clean the rusty tanks ,
mucho shaking of the tank whilst it's full of at least one gallon of
the mix is necessry , your arms will get painfully tired , just keep
at it , have the kids shake it awhile , think of those nice long
drive in your 'Burb catching adoring glances from other AD owners
not so lucky and keep at it...
Rinse well , strain the effluent through some clean cloth untill it
comes out 100 % clean ! .
