1990 300 te 4 matic fule tank issue

[louzbenz904x4]

Hello again, i have recently noticed a fuel leak coming from what seems to be the fuel tank and i am trying to locate a fuel tank , called the dealer and guess what ?
$1500 Can. geez i wonder how much markup they are getting ?
any ways is there anyone who can direct me to a less costly alternative , seems that 300 te models and te 4matic tanks are one in their own for this model , sedan tanks will not work, at least that is what the dealer tells me!
I am keeping an eye out for a used one, but that is a gamlbe in its own , HELP!!
My Family car stinks of fuel , and have no real other mode of transport for my full family .
