I'll look into fuel medic and try that. I was thinking about buying a bunch of sta-bil and using 2 everytime I filled up to see if it would clean the tank.
The mechanic said the pressure was OK. Not sure what to check for the cap and rotor, never replcaed the spark plugs. I used fuel injector cleaner bottles (2) and added to the tank last week and problem still occured. I can use the boat about 1 hour before this starts to happen.
There are no codes that are displayed when a mechanic checked it and no signs of overheating on the temperature guage and I know that guage is working. My mechanic also hooked up a seperate fuel supply and could not reproduce the problem so I don't think it's anything outside the fuel system. I want to troubleshoot before I take back to a mechanic since I've spent about 1200 on the problem diagnosing it and believe to have fixed it and never a true fix. Also the only part that was replaced during that diagnosis over 3 seperate visits to 2 mechanics was a fuel filter change.
Some possibilities I think from reading forums are:
- Fuel pump going bad (one time my gas guage wasn't working and I completely dried out the tank, I heard with EFI drying out the tank can kill the fuel pump)
- Fuel screens, I've seen there are 2 but not sure where and how to check
- Bad gas or crap in the tank that would cause lines to clog, gum up, screens to clog, etc since It goes away for a while after I fill the tank up to full.
- Crimped or block fuel vent line
