OMC Cobra low pressure fuel pump

[BGB0AR]

The chat agent suggested I post my question here. The low pressure fuel pump for my engine is not an available part. The pump works but started leaking at the top of the pump. Might this just be the O-ring at the top connector? Have you ever seen the pump case leak or from between the case and the upper fittings? This is a 1994 OMC Cobra 5.0 MFI #50FACPMDA.
