fuel disposal

[BillPutney]

it's strange how you work on a certain problem and by the time you get every thing put back together , something the was working perfectly will screw up .I drained all the fuel out of my front tank which has never leaked , the minute I put 10 new gallons of gas and a can of seafoam in , I have a leak draining to the bilge and running out the back. So I dug out the jimmy rigged cover over the front tank , it was the area in front of the seat .23 SF 1978 . The whole cover needs to be rebuilt .It is the hinged type . We had someone put the tank in and he took major shortcuts .Should I rebuild the hatches with marine plywood or some type newer materials?
