thanks for the response guys.
slug - the leak doesnt run to the handle ot the keyhole, it runs straight down from the nozzle and collects in a pool where the hook and the lock meet on the thresh hold. the water that comes out is a lot, and its constant. ill take some pics and post them so you can get a better idea of what im talking about.
john - i was thinking of splicing in a valve on the plastic hosing found in the tailgate right before the nozzle. do you think that would be a good location? and what would be the exact name of the type of valve i should be looking for?
