Can I just tap and thread the nozzles into the plastic truck intake? Will this work fine or do I need some adhessive. I really don't wan't to "glue" the nozzles in, I would like to be able to reuse them later. Any suggestions?
Thanks.

 

The problem is that these plastic intakes are not that thick.So you do not actually get that many threads into it.Use a medium grade locktite or apoxe.Its also easer using a pirahna nozzle.

i have done it before. if you dont use any locktite, the nozzle will move around quite a bit but it can be done. there is several people here that have a DP like this.
