FUEL SYSTEM Review...
For those of you with 1973 or later 337's, it might be a good time to review Section 7 of your POH -- the one entitled {Airplane & Systems Descriptions} and in particular the section on FUEL SYSTEMS. The LAST THREE paragraphs really lay it out for use of the AUX pumps. Hey by golly, there must be a reason they call it an 'AUXILLIARY' pump... no kidding!!!
And I didn't mean to exclude all of you pre-1973 Skymaster drivers... it's just that the post-1973 POH manuals were standardized format so that we can all be on the same page. With all of the different tanking arrangements and vapor return lines, a review of your specific POH and/or service manual section on the fuel system is a MUST-DO in diagnosing problems.
