FX-1 Superjet tank in FX1

So I know Idok has one in his. Hopefully this thread can give everyone direction on how to come about this. If Idok and anyone else could give some information on how to get a tank in there and what works/what doesnt work; we would all really appreciate it.

My question, will a mod chamber fit with that tank? What about the tank strap, does the tank go over the strap mount, or does it attach perfectly?

Also interested in how to get the tank in. Ive read the mod chamber will fit with the sj tank but i dont know if a sj tank is just a simple swap or if its not a direct fit.
Extra clearance and another gallon of gas sounds great to me.
 
Ok, here's what you need to do






Install your factory B, ltd pipe..waterbox and exhaust hose just like any other time. REmove the battery box

There will be about 2" between the pipe stinger and opening to the waterbox so you will have to trim the hose. One of those silicone FPP hoses might work great, but we did this with what we had on hand

I used a roundnose waterbox in my boat, it sits in there at a funny angle but is strapped down nice and tight. An Xmetal waterbox woudl probably fit perfectly. Make sure the long exhaust hose isnt kinked..you might have to trim your long hose as well..I had to trim mine at both ends..once for length, the 2nd time was due to a kink..measure twice, cut once.


Here is the key..Hull clearancing

If you look at the pictures, you can see "notches" in the edge of the motor compartment....I ground away the very outside edge of the lip, on the starboard side and forward aspect

this will not reduce the structural integrity....its a very thin edge that gives the compartment a squared off look. In fact, next time I have the motor out Im going to grind that little lip 360 aroound to give a little more room

it wil also make fitment of the tank easier as I could have gone a bit more when did the job originally


that is the key to the whole process....that, and having a 2nd set of hands to make things easier.

Now your full exhaust and waterbox is in, and your lip is ground out.


a mod chamber will fit with a superjet tank, or a stock tank

a limited chamber will fit ONLY with a superjet tank due to the tank design


The next step is to have a 2nd person pinch the long exhaust hose against the hull right above the battery box...While its pinched take the superjet tank and twist it CW while pushing down on it...

it will slip past the exhaust hose and fall right into place....we sprayed a bit of silicone on the exhaust hose to make it slick and it clicked right into place.

I tried to do it on my own for about an hour one night..but I couldnt get it past the hose, push and twist all at the same time.

The battery box will fit right back into the stock location, you might have to trim the front left corner a bit..not much though

I use a battery wedged between the tank and front cover..for this option you will need to use a mini battery


there you have it

Great info Mr. Idok! Question, you said that it was recommended to have the xmetal waterbox, is that because they fit differently then the stock FX1 waterbox. I only ask because if I am going to do this, I am going to run a stock FX1 waterbox.
 
I dont know if an Xmetal box woudl work better or not, but I think they are a little smaller than the stock 96+

stock fx waterbox will be fine...


I used SJ tank straps..


here's is buttis fx....this one has a SJ tank and a MOD chamber...notice the batt box and full size battery

this boat RIPS as well with a 760 61x and 750 kawi magnum pump

Installed my SJ box and SJ tank in my FX today......

Took 2 hrs or so like stated above...

Cut the right side only....

Batt Box is the only problem still....cut a the corner off and the right batt strap clip and still need some more to get it to bolt down...

Did yall just plug the 2nd return line on the right side of the tank tank?

Will be nice to get some better sound and a lil more Gas..
