7 years ran well , then started having momentary loss of rpm but came right back. Now starts right up and runs at idle, pulls away from the dock for a couple of minutes, then won't rev up or even idle after couple of minutes. Momentary pulses of firing and low low rpm with an occasional surge.
so far
1.new fuel lines and bulb from 3 gal tank to motor
2. nothing in first filter, no water in VSD
3. low pressure fuel pump test ok, no leaks , check valves hold proper pressure
4.new high pressure pump
5. inline bulb is firm and manually squeezing does not help
have been assuming its a fuel problem but at this point I'm just treading water and are out of my depth
any suggestions appreciated
