Well I have a 75 wellcraft and I just did this last year.

It is not that hard to get the tanks out.
You have to remove the tank covers and remove all clamps to the filler hose (Going to have to cut and replace these hoses) and remove hose. same goes for the vent hose and supply hose.

Then if they are still attached there will be some fingers tabs at the bottom of the tanks screwed into the floor. They will have to be removed also.

Slide tanks out!! Now you will have to drain the tanks out and find someone who will take the old gas??

After all gas is gone I cleaned well with a degreaser and water. Afetr that rinse well!!!!!!!!! Let sit in the sun for a day or two for the water to dry up.

Reinstall with all new hoses!! and clamps!! You don't want to reinstall with old hoses that may be less then perfect and have a problem!!

Even that I said it is a easy job it would be a pain to do it twice!

After your done you will have a hole new system!

Let me no if you need any more info!!

Good Luck
