Pump failures are somewhat common. The whole assembly is about $900 from Merc, but you can buy aftermarket (or even the OEM Walbro pumps) and essentially rebuild it although the process is tedious.There is nothing in the fuel tank but a pickup tube and a level sending unit. Also, they are not designed to have a primer, use of one can flood the system and cause fault codes.If the pumps are running then that rules out anything electrical for the most part. Although the pumps are wired in parallel so one can fail and the other will still run.You can stick a primer on the end of the fuel feed line to see if fuel can be drawn from the tank, and also to start a siphon. A siphon test will tell you if there are any air leaks in the line, ruling out that part of the system.Priming the system is usually done by cycling the key a few times and allowing the pumps to run continuously for a short while, the fuel system on those must be purged of air as well for it to run, there is no return from the fuel rail.</blockquote>
