Volkswagen Vanagon Bus Westfalia Low milage running project

This Wanagon was owned by one family since new.Last year I found it sitting under the tarp totally forgotten. I was able to find out that owner Volkswagentechnicianpast several years ago and van was just sitting at his old house.It is 100% original and complete .Running but not smooth There must be a problem with air fuel mixture. I checked engine compression and it has 160 psi across.We got it running. It has brand new set of tires all aroun, spark plugs, coolant temp sensor and fuel filet and fuel pump.There are probably vacuum leaks . Fuel tank was drained. After adding fresh one fuel still doesn't look good. I also noticed that there is fuel leak when tank was full.I assume that needs new gas tank and fuel lines.Vanagon is a solid car with some minor rust spots around window moldings etc.Rear hatch was defiantlyrepainted in the past.It is a solid low mileagefoundationfor a great project . All the electrical components are working. It has original tabl, curtains , tabl, rear mat ETC .Very rare option was installed in this particularvan which is rear A/C unit.Odometer is showing only 23000 miles but I was told by the ex-owners sun that has about 65k .I can help with nation wide or international shipping .Van is located in Oakdale NY . Long IslandPlease fell free and ask all the questions .I'm selling it because I have very busy schedule and there is no chance that I can find time to finish this great project.Thank You
