A zip tie will work or you can crimp the dip stick tube just slightly to create a bit more stick-tion.

 

Mine pops when I run my methanol and boost 26 lbs. On pump only and 23 lbs doesn't happen much. I replaced the o-rings on the stick to create more friction and that didn't help. I will try a velcro loop next. For now I have gone with the zip-tie too.

same thing here, happens on stock turbo at above 20PSI.
