Hi 

So I am leaking up a vent line & the tank is 10+ years, some surface rust
not sure about inside the tank, so if I am going to drop a tank & rust proof
the existing tank seem like its just cheaper to replace it with a new tank
at 129US

Has any one tried the above ?
Is the zinc coating inside holding up 
how is the outside rust proofing where they rust around the 
fuel sensor in the recess in the middle of the tank

Also is there any suggestions for canting/grading the fuel tank mounting 
so that water will flow without pooling on the upper side of the tank w/o
adversely affecting the fuel flow  ?

thx tim
