I have a 1996 Fourwinns with a 5.8 fuel injected motor. Last season I went thru 3 low pressuer fuel pumps? The last one only made it thru one day. They don't fail and stop, the boat just won't start again. There is not a strainer on the pick up in the tank. Replaced the check valve (old one was fine). Changed the fuel seperator filter. When I put the new pump on the boat starts and runs fine. Untillm it wont start again. Anyone have this problem.
