CouperKarl aka ProEd, Altimeter Loosey-Goosey is most likely from the lack of a static system and being vented to the cabin. Cabin pressure is fluctuation as air flown over the windows and is pumped through opening in the fuselage. A new altimeter will not fix that.
Fuel Leaks: We've got some experience there. We removed the tank, resoldered leaks, and replaced the felt cushions. Tightening the fuel tank straps too much caused structural failure of the solder joints and fuel leaks. mitch -- Learn2fly www.chickashawings.com
