Quick question. I picked up a Stenner adjustable model on ebay pretty cheap, (the 45M5 model)..but it did NOT come with the connection nuts or ferrules to connect the 1/4" tubing to the pump. I looked at the Locke Well & Pump Company website under their "connection parts" and the only thing they have listed is 3/8" size....I don't think this is the correct size for my pump and tubing is it? Where can I get the correct ones???
