I have a 3250 watt Powermatic generator that I bought years ago. When I bought it, it had a cracked block and a tank full of water. Replaced the block, and patched one hole in tank. Used it during snow storms and hurricanes. After hurricane Florence, tank developed another leak, many of them. Bottom of tank looked like Swiss Cheese, so there was no more patching it. Contacted several sources about another tank, but no luck. After doing some research, I figured that Septa 6 gallon, under the seat portable gas tank would fit the confines of the frame, but I would have to build some brackets to hold tank. Because it's a boat tank, it isn't gravity feed. This meant I would need a fuel pump. Have an old Honda engine that has a pulse fuel pump on it, so I decided to try it. First I needed to get a source of "pulse." Took the valve cover off another engine, drilled and tapped a hole for a 1/4" hose barb. Connected pulse line from hose barb to fuel pump, and then connected fuel pump between gas tank and carb. Purposely left fuel line hose long. To prime it, blew into fuel tank to force some fuel into pump and carb. Because I haven't built the brackets yet, tank was located a couple feet off the generator on top of a milk crate. A couple pulls, and she was up and running. Put a load (a fan & light) on it and ran it for a few minutes, with no problems. I think I will leave tank so it can be removed from generator and remotely located. This way, I could refuel it while generator is running if necessary. I love it when a plan comes together.
