Paul, those are HS's (not HIF's - those were fitted beginning in '72). I
know this is an obvious point, but it has to be addressed first: did
anything happen or did you work on anything immediately before the condition
began? Or was this a gradual development? Sudden fuel use like that makes
me wonder about floats. Do you have any overflow into the carbon canister?
