A4 Fuel Pump
I replaced mine twice. First time around was with a Facet one the Moyer sells. It failed after less than a year, so I decided to see what else was marine rate. NAPA carries a Sierra electric pump which is very large and very heavy duty. I've had if for a few years with no problems. I did, however, install a very large RACOR fuel filter/seperator since I felt the old tank has a lot of S&^T in it that may have been influencing it. The pump and filter are both rated at over 80 GPH, so even with a little pressure, it put a strain on it. The guy at NAPA says he sends boxes of them to Alaska each year when they rebuild the fleet boats up there and has never had one returned. I know that their was a series of the Facet pumps that had a design or workmanship issue. Either way, about 180 for pump and filter and I've been real happy. When the old fuel pump failed, I did find a non marine one for 30 bucks at a local automotive place that got me home. That is the key reason I like electrical, easy to get a replacement. The NAPA one is marine approved.
A proper fuel filter is important though.
