1959 Johnson Sea Horse Metal Fuel Tank

[sailforth]

I need to replace this tank. It has double lines, air and fuel with a thumb pump to pressurize the tank. Does anyone make a plastic tank I can use? If not, where can I get a new metal one?

Hi Sailforth,<br /> Used ones in various conditions turn up on eBay all the time. 1959 was the last year of the pressure system on Johnruds, so finding a new one is going to be next to impossible. There are rebuild kits available through several sources (www.vintageouboard.com) and hose is available at NAPA, etc.<br />- Scott

Do you want to replace or rebuild the 59 tank. I have a 59 35hp johnson and I went to Wal Mart and bought a plastic tank and new line with Johnson fittings. Works great, cost about 20.00 for all

Baitkiller,<br /> The '59 35hp and 50hp used a fuel pump, while everything 18hp and below used the dual line system. By 1960 they were all converted to fuel pumps...<br />- Scott

Baitkiller, can you enlighten me a bit more on how you converted a new plastic tank to the old style? Where'd you hook up with the Johnson fitting? I have the same setup on my '59 18HP Seahorse, and the tank is getting ratty.<br /><br />Thanks<br />Rick K

Rick K, You can not substitute any other tank (plastic or otherwize) for the original OMC presure tank. You my how ever convert the entire fuel system to the more modern pump system. This would allow you to use the plastic tank. To do this would require the purchess and installation of several parts. A fuel pump, fittings, tank, hose,ETC. If you use quality OEM parts, this procedeure can get to be costly. I will be honest. I still try and use after market fuel hoses and fittings. They suck! I will not use after market plastic tanks. They really suck! Lately I have been buying plastic OEM tanks. I am sure thay are made buy the same after market company as the cheep tanks. The OEM Tanks seeem to have better fittings.In your case, since you allready have a working presure system. I feel you would probably be money and dependably ahead to clean up and over haul your present system. This would consist of disassembling the tank, cleaning it out, painting. Then replace all rubber stuff (gaskets, hose, o-rings). The O-rings in the fuel line connector are replaceable. You should be able to rebuild one of these tanks (presure type) for under $50. including cleaner and paint. It only requires a few miniutes to change out the old gaskets, most of the time will be consumed cleaning and painting.

Alcan, thanks, and I agree. I had thought that there was perhaps an easy conversion out there. The tank I have now holds pressure; it just looks pretty bad. And, I was under the impression that once all the stuff on the top unit of tank went bad, I was s.o.l. Gaskets and O rings are readily available, either made up or home made.<br /><br />I'm not gonna tear into that until it's absolutely necessary.<br /><br />Thanks<br />Rick K

Dear Sailforth, I have a 56 johnson 15hp. with the double lines to the tank. With our motors, we can't just swap the tanks with a new one, because out motors aren't equipped with a fuel pump. The air line carries crank case pressure back to the fuel tank to force fuel back to the motor. You tank might have a pressure valve somewhere where you can pressureize it with an air compressor to help start the motor. I just found that out myself. Could you post a pic of your tank if possible. I would like to compare it to mine. Thanks and good luck.

Re: 1959 Johnson Sea Horse Metal Fuel Tank

OMC offered pressurized fuel tanks in an updated (5 Imperial, 6 U.S.) gallon size in the 1970s as an accessory. It came complete with dual lines. It went by part # 377331. I have seen them in the 1973 OMC Accessories brochure. They are also shown in my 1974 & 1976 brochures, although I think in those the picture is of a standard non-pressurized tank. They were $48.35 (double hose included) compared to the standard non-pressurized tank at $28.75 plus $9.10 for the hose.

They must have sold some, so they must be out there somewhere.
