Narrative:
On jan/xa/06; I worked an ETOPS operation. I noted a prior deferral of PIREP l-hand engine fuel pressure indication per gpm 17-01. Noted that the fuel pressure indicator is a maintenance function only through EICAS 014 and selection and 'cont' deferral. Deferral was questioned by pilot; concurred that gpm 17-01 at that time may be used. Reviewed MEL general section and gpm 17-01. May have misinterped the applicability of gpm 17-01 in this case.
