"A" is your inlet and "B" is your outlet. ESB 42 shows a different orientation of the upper section of the pump (by two holes, requiring rotation of same) which was not been done on your plane. It gives detailed instructions how to do this. This list had recent threads discussing whether the use of automotive fuel pump parts was legal on Ercoupes. On this subject, in 3.a.2. ESB 42 states: "All fuel pump parts necessary for repair are available from the Continental Motors Corporation, AND AC AUTOMOTIVE SERVICE STATIONS". (WRB emphasis added) Perhaps this ERCO/Univair statement is clear enough as to the automotive origin and parts acceptable for use in the "Continental" pumps fitted to Ercoupes. They were (and remain) automotive pumps with a Continental actuating arm, and nothing more. ESB 42 also shows the original push-on hoses and hose clamps. Your plane has been modified with modern aircraft hoses (Aeroquip?) and fittings. Accordingly, you can not just order the Ercoupe restrictor fitting, Part Number 415-48101-40, since it requires a push-on hose. To be legal, there should be log entries for this modification, although I do not know if a 337 is required. Functionally speaking, there is no obvious reason not to have your present outlet fitting brazed shut and the required 1/16" hole then drilled in the braising. Again, a log entry would be appropriate to document for later examination to confirm that you DO have the necessary restriction in the fuel outlet since this would not otherwise be confirmable without disassembly. Note that your present installation paces your outlet hose about where chafing failures made this service bulletin necessary. Regards, William R.
