Good day ,
im having an issue with fuel contamination on my outboards.
The vsts were removed ,cleaned, replaced HP fuel filter , after 12 hrs working time ,one outboard bogs down and doesnt want to rev past 3000 rpms.
Removed HP fuel filter and found it was black,cleaned it out with carb cleaner and found that the liquid coming out of the filter was black.
Removed VST again and found it was clean,no black deposits in the tank or the fuel.
What could be causing the filter to block up so quickly?
Checked all fuel hoses coming from fuel water separators to primer bulb and all hoses from primer bulb to the primary strainer on the outboard,they all fine and not disintigrating inside.
The fuel in the strainer and fuel water separator is clean ,as well as the fuel in the bowl of the vst.
Any ideas ,what could be causing the filter to block up so quick.
Tested the boat on the water and the outboard ran fine for 3 hrs and then back to doing the same. The other outboard was fine.
Please , any help is appreciated.
Thanks in advance.
