ok just found a post on page 51 (suction pump) what about the stud removing idea does the stud hole go right through then i could replace with a bolt for ease of draining next time :popcorn:

The stud has a head on the back,it is not just a straight thru stud.You have to remove the pumpkin to change the grease.
