Hey crew, anyone have a suggestions on removing stripped fuel sending unit screws? Last owner (don't know who that is) put plumbers putty all over the sending unit connection to cover up a leak instead of replacing the sending unit. I have a new sending unit but the heads on the screws are stripped and I will be emptying the tank and dropping it but looking for best and quickest way to remove the screws. Any help would be great!

Thanks.
Ed
