Race gas seems to be the death rattle for these...BUT... not all race gas.
I soaked one in VP110 and one in 100LL AvGas... the VP softened the adhesive on the filter... the AvGas... nothing.
Also.. the old filters back in 2006 or so, didn't seem to have this problem.
Race gas has strong solvents in it like Toluene etc. that will soften a lot rubbers/plastics/adhesives.
Octane boosters are the worst it seems on the filters LOTS of toluene in there.
Funny, on the 2015 AXYS sleds... no external fuel filter... the pickup sock in the tank is the only filter.
