I pulled the tank to clean it out and change the pump/filter. What a mess!! DON'T let a running car sit for 10+ years!! The only reason he parked it was the clutch started slipping. He was driving it daily until then. Now the whole fuel system is trashed.
Inside the tank
After a trip through the radiator shop's tank and a wash with muriatic acid.
Cleaned up the sunroof seal.
