I have a Johnson Seahorse RD-15 25HP outboard, and also, what I thought was the right gas tank to go with it. I had it up for sale on Ebay, and someone told me that the tank was not correct, and it wasn't pressurized. I wanted to check with you to see if that was true, as the gas tank hookup fitting, does fit my Johnson Rd-15. We haven't tried hooking it up and running it, as my husband doesn't have the time. I'm attaching some pics and asking you experts, if this is in fact the wrong type of tank, also if it is wrong, how do I recognize the right one? Your help is much appreciated!<br />
