Here is Tom's site and a link the page on how to eliminate the need for a pressure tank/two line system on older cd series Johnsons and Rudes.
I myself use this to convert my 1954 CD-10 5.5 Sea Horse, and use the exact Mikuni pump he shows, it's simple and works flawlessly. Best of all, I can use my newer tanks, ever priced out a a decent pressure tank with lines on eBay, it'a sobering experience:D

That's one way to do it, but he's entirely wrong about the old tanks being dangerous time-bombs. They are perfectly safe as long as you maintain them properly...that part is HYPE.

Yep I totally agree. Reguardless of how you look at it, a tank of gas is a bomb, whether it is under a slight bit or pressure or not Those pressure tanks work just fine, if they're not rusted out.
It's all in how well things are maintained. A good rule of thumb: don't smoke in the boat. There's a tank of gas 10 feet from you.

Alot of the pressure tanks, given their age, need to be updated. Once they are, or if they have been well cared for over the years, there's not much to worry about IMO. I have seen a line break, and gas spray throughout the boat, on someone at my marinas boat, but once I inspected the line I found I could snap it in half by bending it. It was likely 50 years old! His fault 100% in my opinion, not the pressure tanks.

If you get a pressure tank, go on ebay and order a restore kit, and you wont have any problems. Shouldnt need any clamps on the hoses, but for safety reasons, cant hurt. Common sense also comes into play here, if your tank is rusted through at the seams, time to get a new one. Go to an AOMCI meet, and there are plenty of guys that sell tanks that are clean inside, but need updating for like $20. Buy this kit

and if you want to get fancy, get it soda blasted, paint it, and buy a couple new decals for $5, and you have a nice looking, age proper, pressure tank that will last for years. I skip the rebuild kits myself, and fashion my own. A little leg work matching the gaskets, and a little time making patterns for the gaskets, and you can cut down on the cost of rebuilding them. Only money I would put out is to get it soda blasted, as most are varnished inside, and Im much too lazy to soak them for weeks and sand the exterior. Soda blasting cleans all the varnish out, and stips the paint, leaving a nice clean surface to work with.
