    Hey guys, got about 3500 miles on my Terra now. Last night I noticed my inner right leg felt wet, thought maybe I was just being crazy. Then today after I filled up I felt it again. This time I felt my jeans and my hand smelled like gas. I popped off the seat to find gas coming out from around the fuel pump (Right from under the black metal ring in the pics below). I popped off the line, pulled out the pump assy (which looks like it came right out of a car btw) and pulled some fuel from the tank. Cleaned everything up, checked for cuts or nicks on the seal, found nothing. Put it all back together, no leaks but the I pulled like a gallon out plus what leaked out on my ride. Went to the station after it sat for a few hours, popped the seat again and filled up. Right after I was done pumping it started seeping again. Gonna call the dealer tomorrow or Tues, whenever they open. Does anyone have any ideas? IMAG1179.jpg IMAG1182.jpg

    Is the tank vent is free flowing....looks like high tank pressure to me. Do you still have vap can on bike?

    I feel stupid for not checking that to tell you the truth. Like really stupid lol. That would absolutely explain it. I'll check that when I get home, where is it located?

    Anyone know which sealant I should use to seal the rubber tank/pump seal to the tank?

    I have the same issue on mine after only 1300 miles. Before I go through this, did it actually fix the problem? If not, how did you fix it?
    Thanks heaps.

    I removed the charcoal canister and did my best to seal the pump back in without a new seal as one was not available. I used jet fuel tank sealant I had at work. It held up until last week or so, now at 7500 miles I have a new oem seal to replace mine. I'll update the post again after I replace it. Should be able to do It tomorrow.

    I also gutted the gas cap vent of the check valve so nothing can slow the tank from venting.

    For no other technical or educated reason, but onlly becasue fueling the bike made a fountain spray instead, I removed the red "sleeve" at the gas tank opening - I think this is only on US models - but I wonder if anyone else has done it and found whether this makes a difference in the tank pressure or other issues. I also don't have the weather or enough miles yet ( < 1000m ) to have tested the pressure issue. And I'm not excited to find this problem either. I will take another peak under the gas cap to see whether the ball, spring and washer that High Five found are there... Any ideas why that skinny red sleeve is in there in the first place?

    I'm assuming the red plastic is for the same reason cars have restrictor plates in the filler as well....to prevent someone from inserting the larger leaded or diesel nozzle. It was a bigger deal back when transitioning from leaded gas, but since leaded gas is all but extinct on the highways, it shouldnt be a problem. Note that some emissions testing may test for the restrictor and could fail you if its not there.

    If I show up at the emissions testing place and pull the red sleeve out of my jacket pocket, think that'll count? :p

    My Aussie TR never came with one, must be only the US bikes? Think hasenpfeffer is right

    I removed the red plastic sleeve from the tank shortly after I bought my bike.
    Like you, I had problems with gas spraying during fill ups.
    6000 miles so far with no issues.

    I can easily squeeze a bit more fuel in the bike without that thing in there too.

    Ditto as it took too long to fill the tank with the sleeve in place. Don't overtighten the filler cap screws as you'll squeeze the seal. Two years later no issues with leaks.

    Mine got repaired under warranty. The entire tank had to be replaced, My friend owns the dealer who did the work and he said it was a Nightmare of a job to do. I sold the bike before it even left the dealership. Had the new owner pick it up there. I didn't even want to see it again.

    Hi jetsun, can you see any cracks? in the poly flange or around the nuts. Did you torque the bolts to spec only? Is the ring in shape?
    JBweld does a epoxy gas tank repair kit. Avoid silicones mixing with fuel, known to damage O2 sensors.
