Fuel went in great but don’t know if it pumping at a high enough rate, doesn’t seem like it getting enough fuel yet
I ordered on Friday afternoon and had it the next Monday regular delivery by usps!! Installed easily and worked perfectly on our houseboat. Will order another as a spare for the other engine.

Time will tell on longevity, but the fit and finish on the pump are great. Seems very well made. Perfect fit for my Mercruiser Mag MPI. Fixed my low fuel pressure issue! Engine started right up, pressure back to 30 psi.
