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.
Sent the pump quick and works great
Fast delivery. Exactly as described. Perfect fit. Got me back on the water within a few days.
everything in the order process was awesome came in two days but still winter here and will be installed next month when it warms up so I could answer better after that
