I have a 2 Mercury 2002 90ho EFIs. One motor recently had the voltage regulator burn up. The boat has sat for 3 years up until I purchased it last month. It ran fine (probably 2 hours ) until the regulator issue. We had the regulator replaced and it still will not run. The tech took a fuel sample and showed me black specs in the bottom of the bottle. He said we need to replace all the gas lines and clean out the VST. I believe I do not have the latest and greatest Mercury gas lines. In addition he thinks we need to put a water separator/filter on the main gas line.
I have 2 questions1) Mercury advises not to put a separator/filter in because it will starve the system. Is this correct?
(2) Is the little black sandy looking particles from the fuel line and if so should it take him 3+- hours to rebuild the VTS and replace the lines?
Thanks
