3/8" tubing connections

Here are pictures of some connections using different fittings on 3/8" tubing.

Splax Excellent photos! This is a big help. THANK YOU!!!

Splax/Jacques Did either of you replace the line coming from the aft water tank? If so, what is the best way to access the connection? Thanks... Jon

The aft bulkhead is split. You only need the Port bulkhead piece removed. You need to remove the trim pieces (port overhead, bulkhead top, bottom & joint cover piece), then work the port bulkhead piece free. Take your time prying to get the wood loose. The water line runs under the aft berthing, behind the aft storage, nav station, behind then down under the settee. Take your time fishing the line through. The line is zip tied with wiring in several places, so do not get in a rush.

Splax, Thanks for the info and advice!

Pex is arriving today so I'll begin the project tomorrow. Found what I think may be a good supplier... SupplyHouse.com

I really hate how they zip tied all this stuff together. Especially the zip ties under the sole. -Jon

Splax explains it pretty well. I was able to get to the zip ties and cut them. It helps to have one person pushing while another pulls.

Update… While I was planning to begin on Saturday, the Admiral had a different plan, so work began on Sunday. Note: I decided to use 1/2” PEX as it appeared there were more fitting options available for that size versus the 3/8”. I began by pulling a new line to the aft tank. Took Splax advice and removed some of the plywood under the cushions in the aft cabin. This allowed for a couple of additional benefits… 1) Cleaning all the gunk/dusk and other elements that have found their way in several previously inaccessible areas and 2) I was able to better secure the wires and water lines that ran below.
The most difficult run was the athwartship lines. I took Jacques advice and was able to get the admiral to push while I pulled…. This took about an hour. I had to remove the Forward dinette settee and move the poop tank to gain access to the lines as they emerged from under the sole.
I junked the 3-way tank selector switch in favor of a simpler (see attached pic), hopefully better method.
Found lots of dried Plumbers putty around existing pumps (1994) outlet. That certainly could have been where the air was getting into the system. Ordered a new Aqua King II junior water pump.
Hopefully, it’ll be done by the weekend.
I sent my Dad some pictures of the cabin. He wondered if I spent more time taking apart and putting back together the boat more than anything else…. My answer was… Probably… but that’s have the fun.. and it keeps me off the street… for the most part.
