Hello,
I wanted to post this due to everyone saying it is not important to change your grey tempo vent lines on RFI models. But I have brown goo in mine! I pulled my fuel pump assembly out of my 99 GSX RFI because of a possible fuel issue. I found brown corrosion at the very bottom plate next to the inner filter. I then noticed streaks of brown in the inside of the cylinder and a few on the outside. They were not splatters so it was not from the fuel pump itself. Then I looked to see if it came from the fuel regulator. It was clean underneath. Then I looked at the vent fitting that sits on the plastic plate that holds the regulator. There was a buildup of liquid brown goo! I then saw it came from the tempo vent line.
The story of my seadoo is that it didn't go in the water for 4 summers. I would run in at home 1-2 times in the summer just to make sure it was still running. I put some stabilizer in the fuel but never changed it. The tank was more than half full. We have about 10-15% ethanol in the gas at Esso where I buy.
My best theory is the evaporation of the fuel went into the vent line but rested in the first section of the line. Over time the line broke down and leaked the brown goo down into the fuel tank assembly. It settled at the bottom, sat in the fuel and got really hard. It also caused pitting on that bottom plate. I had to use a dremmel with a wire brush to get it all off. The attached pictures only show the assembly after I cleaned it. But you can see a bit of the brown streaks.
Yes I should have taken better care of my seadoo, but life sometimes gets in the way. It only has about 40 hours on it in 14 years.
So this is my warning to those with RFIs, watch for possible brown goo from the tempo vent line.
