Hello All!,

Dropped the fuel tank on my old fourwinds motorhome and it was completely rusted out.

I need to replace does anyone out there know where I would start looking for something like that?

 

If you managed to drop the tank already, then it is either safe to assume you had the proper tool to remove the lines or you improvised and will need some special extra parts.
Your best bet to get the right parts the first time , I think, would be to go to a Ford dealer parts dept with your vin # and all info you have on the vehicle. They should be able to get whatever parts you need unless something was installed by an aftermarket upfitter.Then it gets complicated. The dealership parts dept usually can come up with the right parts for the chassis unless something was changed after the vehicle left the dealership. Sometimes a local auto store will do that for you, but they will have to go to the dealer also.
The additional info you should get is usually on the label on the driver's side door pillar. Like WB ,wheel base etc.
