Nice explanation, easy to follow. I myself will stay with my pressure tanks. All the internal parts are available and are rarely ever needed, the line is available and the fitting o-rings are easy to change. I’ve also collected a good number of both fitting and tank and bought a 100’ of line,, I think I may need another🤔. I like enough to reach the bow of my tinners! And I think I’ve got three or four all rehosed plus a couple for friends. Cheers! Keep it up, keep em running!

Thanks Mike. Great video. I have a 59 5.5 fisherman. runs great. Can you explain why I very suddenly have a bad leak at the fuel connect. It sealed just fine and now leaks like a sieve. The receiver seems fine and the springs are working. If I can't get it to stop leaking I'll try your conversion. thanks in advance.

There are two chubby little o rings in that connection, they are still available at dealers and likely Sierra etc with the use of a couple of pics you can compress the shut off in the center and pic the O-ring out give the inside a good cleaning and blow if possible (they can be gummy etc) then install two new ones. Quick note, if only the air side is leaking it can cause issues with stalling and leaning out. I prefer dual line, I find the above mentioned connectors much better the line itself more durable and by far the biggest reason is those damn primer bulbs. They either refuse to work are turning to rock or split and leak. I have only come across one tank that won’t push fuel back and it’s likely the pickup tube inside. Also the kits are available to overhaul the dual line tanks.

I have received my Kohler Pump, I've removed the flapper valves and plugged the one port so I get a pulse. I've mounted the single line fuel connector in place of the two line connector. I was concerned with the large size of the connector's hose barb, but see that it matches the fuel pump's hose barb so I'm ok there. What I'm concerned about is 2 things: 1. the pulse outlet hose barb on the engine is a lot smaller than the hose barb on the fuel pump. SO do I stretch a small hose over or clamp down on a larger hose? 2. Same problem on the carb. It's hose barb is a lot smaller than the "carb" fitting hose barb on the pump... Stretch or clamp down?

You are the best T-Mike! I’m a novice mechanic, driven in my restoration of an old Old Town dinghy nprimarily by my carpentry skil, but have managed to make the fuel line conversion with your guidance here ( for a 1957 Johnson 5.5). It’s a miracle! (I have had the help of a mechanically inclined friend). But there’s a problem I think in that the installed fuel pump drips gas out of the screened opening in the middle of the pump. That’s got to be dangerous. It’s the second new fuel pump I’ve tried, with the same result. Today I finally got the motor going, and ran it for 5 minutes, but was afraid of taking it out and creating a firebomb. Any idea what’s going on?

@@michaeljsimon Thank you; you have helped. I have two tanks. One is an Atwood bought from West Marine. It says it is a pressurized tank. It has a single hose connector on it, and I do not see any venting mechanism. The other tank is one of the old metal Evinrude pressurized tanks made for a dual hose. The dual-hose fitting on that tank has two plunger rods which get pushed in when a dual hose is connected. One plunger opens the pathway for gas to flow. The other opens a pathway for pressurized air to be sent into the tank. I may be misunderstanding what happens to the "air" plunger when I attach my single hose. I know the plunger is depressed, but does that create a venting in my case? Both tanks work with my single hose, but the motor seems not to be running as fast as it did with a dual hose. That was made me wonder about venting. My motor, incidentally, has a fuel pump that is attached to a bypass cover, and the outlet nipple on the carburetor manifold that once sent pressure into the fuel tank has been capped. Once again, thank you for your knowledge and help.
