This...Verify the gauge is right too. Needle and seats, as stated, I've had the O-rings shrink and not seal. If you screw the thing out and pull it out of the bore there should be a little felt resistance if its snug enough in the bore. Make sure the floats aren't heavy too.



There is no resistance at all o rings definitely look smaller and not plump.
All 4 are bad.
Never seen this happen before. This Q16 stuff is nasty.


Pump gas is also not good on this stuff. Have had this occur before. O rings shrink and get hard.

Q is not supposed to be left in the fuel system. Says on the can.

If the results don't match the theory, change the theory.
