Yamaha 250 issue

[McGillicuddy]

I found this little chunk of what looked and felt like silicone stuck in my supply elbow at the back of the tank. Maybe previous owner had used silicone to seal a fill cap, or fuel sender or something. Phase separation?

I had a big block 69 charger someone put a window cleaning paper towel down the filler neck it would float around and the. Wrap around the pickup tube and stall the car untill the suction let it float away then it would restart and might not act up for a week drove me nuts

The silicone omg the pickup would account for one motor - this is happening to both.

If something is in the fuel tank - there doesn't seem to be an easy way to remove it - or to confirm that something is in there.
