    Fuel filter gunk

    Yesterday out for a ride on my STX-R, had just filled up at shell on the way to the lake. Got through about half a tank before ski started cutting power. Check the fuel filter and a ton of gunk in it, looked like old ethanol and even some shiny pieces of something. Cleaned the filter out and kept riding, when I pulled the ski out of the water there was some more gunk in the filter. Will be replacing the filter, but was this most likely bad gas from the station? Have never had this issue before with the tank, probably have been through 40 tanks of gas with the ski. Also, do I need to open the carbs back up now to check for blockages if some junk got past the filter? Not sure what my course of action should be here, if I need to clean the tank out as well.

    Hard to tell. I'd probably pull the fuel pickup out and take a look inside the tank. If you see a bunch of brown goo that looks like Permatex gasket sealer, you'll need to clean the tank and the carbs.

    Just don't let it run lean! If you're running fast and it starts to die on you, idle it back to shore and fix it.

    Thanks Steve, I’ll pull the pickup and have a look inside. After the first time clearing the filter everything went back to normal, no cutting. Ran WOT for about 10 seconds to test on the way back to the ramp with no issues, but found more gunk in the filter at the ramp. I may just pull the carbs back off for peace of mind, but I’ll inspect inside the tank first. Definitely don’t want to run lean and blow something up.

    Finally got around to inspecting inside the tank. There is certainly some junk in there. Any advice on how to clear it out WITHOUT pulling the tank?

    Funny you mention that. I have the same gunk in one of my skis after I put premium in it. I'm in Wisconsin but it's still weird. Same can I've always been using and never had a problem with either. Really odd.

    Steve what was your go to solvent for cleaning fuel pump gunk?

    I need to do something with the pump off my old jeep, Iíd replace the entire module but they are over $150, I have a suitable pump on hand but the bracket is just nasty

    Somebody may have swapped the tank in the past do there is a 50/50 chance Iíll end up with the wrong module

    A three year model, luckily I didnít have to drop the tank to remove it

    The pump is side mounted! Why they did that is a good question

    99% of auto pumps go in from the top

    I use lacquer thinner.

    Side mounted? I had a Jeep with a side mounted fuel pump--on the side of the engine. 360 V-8 in a 1983 Waggoneer. Second worst vehicle I ever owned! (I married into a 1974 AMC Gremlin, THAT was even worse).
