The Mod Shop has a production line of refueling systems that work only while the engine is running.

This simple yet extremely vital part is a must have for offshore and endurance style racing.

The kit adds and additional 10 gallons up front of the Ultra. Kit also includes a relocation kit to move your battery and ECU ensembles.

First part of this kit is to remove the front bottom bucket from the craft. This was done for several reasons but most importantly was to allow for maximum fuel capacity. Bonus I found was a tremendous amount of ventilation gain.

I found that on a few of the crafts we fitted that the main stock tank needed to be scooted back. It seems that the stock location has some tolerance that allows the tank to scoot forward and the tank shoe doesn’t align properly. I used a crow bar and simply gave it a small scoot.

Once that boring job is done then you can fit in the tank shoe that forms around part of the stock tank and the extra tank.

You ll notice the mounting bars for the Relay and Battery are inbeded within the fiberglass. To mount the kit down youll use the stock location of the battery tray. Be sure to use RED loctite in this location.

Also notice in the pic above that I had to cut a small corner off the left side foam. This was to allow clearance. Some may want to keep it there and just allow the shoe to squeeze to it.

Also notice the red strap I used as its a security ratchet Im adding for rough offshore use.

The kit does require you to mount the ECU to the side wall of the craft. Understand that this System was design for Race boats or crafts used ion competition.

Pic of that location coming……

Once you have your ECU and relay switches mounted away and safe the you cn move onto strapping the battery and installing the battery brace.

The strap and brace are definitely hardcore and ensure absolutely no movement of the battery. The kit comes with traps attach to the front stock tank clips. You will be adding an addition strap to those hook to come over the battery. The mounting brace is the aluminum bar that mounts to the center section of the hull under the instrument display.

I opted to go with the kit that does not have a filler neck.

Drop the tank in and strap it down.

Pic below is the extra precaution I did to ensure a corner attachment to aviod shock from under the hull.

The tank used is a actual Coast Guard aproved tank ment for use within a watercraft engine bay. The eaxtra tank is also extremely durable and takes to abuse of offshore use extremely well.  The system works with the ventalation tube and pulls fuel from the extra tank when the stock tank fuel level drops it automatically replenishes from the extra tank. Esentially it burns from the extra then when that runs dry it pulls from the stock. Great thisng about this design is that if you like you can use your craft as it was stock and only fill the extra tank when extra milage is required.
