removed fuel tank and pressure tested. found 2 leaks at tank access plate also: -no anti-rotation plate installed on fuel pick-up tube -rubber gasket installed on sender (manual says do not install). Gasket was cracked with age in spite of no use.
Above sqwaks (except leaks) were due to revisions to plans after original owner installed plate.
tested fuel pickup with ohm meter, checks ok.
Reinstalled fuel tank, need to order new access plate and gasket and anti-rotation
