2002 Mercury 50 EFI fuel pump pressure

The motor started and was running on for less than 5 mins. It stalled and now will not restart. I am leaning towards a fuel problem. I tested the high pressure pump and while it is cranking it only has 15lbs.From what I have found it should have 40-42lbs. Can anyone tell me if this is correct?

Thanks, wetsquirrel
 
Hi .I have A 2002 25 HP Mercury Outboard engine. I m having problems with the fuel going into the engine. It will run a few minutes when the bulb on the gas line from the tank to the engine goes soft. When I squeeze the bulb, the engine revs up again and continues to run for a little while. I replaced the gas tank and new bulb with a new gas line. I also bought a carburetor rebuilt kit and had the carburetor rebuilt. Still having the same problem. Any ideas as to how I can resolve this problem without having to buy a new engine? Your response will be greatly appreciated. Thanks, Mike A
 
Wetsquirrel sorry I do not know.

Mike A. Could be fuel pump. I rebuilt mine. I think it cost around $15.00. Easy DIY if your handy.
