they are splice kits with a drain plug in the splice adapter. Came up with those many years ago. Since this thread I am sold out now. More to be made soon. You can drain these by the drain plug or just the pull hose off the back end whatever is easier .

There will 2 versions made inwhich I have a good idea to add something to the splice adapter.

There is guy up here a couple of years ago or maybe longer than that --- posted he had a 496 with a unfound leak for years, He called me and I told him about where the leak was coming from and I had the inexpensive fix. I think he replied a thx to me and it fixed his unfound leak. It was from the drain actuators.

How I found these leaks around mid 2000 s was I put a camera video in the engine compartment with lites and went to the lake. What I found was alot of the actuators drains leaked at high rpms for a short jist. Some leaked more than others but for the most part many did leak. At that timeframe there was about 200 - 496 s coming thru my shop per year. Many were not that familiar with 496s nor the scanning of them.

back then the main issues were IAC failures, foul spark plugs, water pressure alarms, some blown up 496 s, scared impeller housings, exhaust temp alarms, engine overheats some boost fuel pump failures and so on. And for the record not many even heard of an IAC muffler.back then. When would tell customers and even some dealers that the IAC muffler needed changing they would laugh and say thats funny because they thought it was joke and something we made up. .

BUP - any idea when you will have more? Im currently trying to find the rebuild kit but not having any luck and the whole drain actuator is NLA.

Thanks.

There is a Tee fitting 861505 which was used to drain the water out of the line going thru the first Gen cool fuel. I took one of them and added it at the raw water pump output side to drain water. Could also use on intake side
