Gasoline Line Leak

95T100XcabSR5...190K...gas leak at rubber backet above top edge of tank holding both fuel and return lines...what is easier
1.Drop tank to replace lines...or...remove bed and service
2.Can someone confirm steps for both procedures
3.Can I simply replace bad section of fuel line or should entire piece be replaced
4. Anything better to use instead of the steel line that obviously corrodes
Thanks for help in advance.

It's your fuel sending unit that is leaking.. It's not hard at all to drop the tank... I just had to do this on my 1994.. I replaced all the fuel lines while I was there and got a new fuel sending unit from toyota.. The new unit is $79... I installed all new lines for less than $30... Best move I ever made.. I'd replace the fuel filter while under there too.. More than likely its all rusted.. Hope this helps
