Beware: this kit does not adapt directly to the GAST vacuum pump: tubing ID is 1/4. Pump requires a 3/8 ID. Purchasing a 3/8 ID tube at homedepot did the trick for the connection. Also - the kit does not come with T-barb so you need to purchase independently those for a resin trap if you have concern with resin getting in the pump.This tubing is pricy. I replaced the few last inch between the suction cup and the trap with just standard clear tube so you get the benefit of the long sturdy tube for multiple jobs.
