Saving Old Seagulls

Is there a long range tank for a 102?

Also I seem to remember seeing that someone had used an old cap and made a hand pump sort of refuelling unit that they could use whilst they were under way .
I wanted to go on a longer jaunt (over 4 hrs) and didn't want to be caught in chop, hanging off the back end of my tiny likely hobby-horsing double-ender trying to refill my tank.

Like this one....

Can I have it??? haha
Is that a gallon tank like the squarish steel ones they made for the other models?
I have one of those, but I haven't seen one of the large round ones around these parts

Long rang tanks are very hard to come by So this is what i use. But if anyone in in Australia has a long rang 102 tank needing a very good home? Please.

With Thanks to Cam Sutherland.

Simple Painless and works very well.

Having a long range tank means you don't have to fill it up as often, which is great when combined with the filler cap I did above, they can be done with both the ali and black fuel cap just make sure if you use a black one not to heat the brass insert when drilling or tapping as it could spin. All of the racers over here use this type of system one way or another some have added float indicators and breather tubes so if it overflows it doesn't pour petrol over the tank on the nice paint.

Cool! I like that unit
Thanks!
Now to prevail upon one of my tap and die wielding brothers

I guess the idea with the breather hole is to have it on the aft end of the cap once it's tightened down?
or keep some sort of tiny plug handy for when it's tilted (which for me is usually most of the time unless it's necessary to motor)

So, can you buy the kit to do this - and, if so, where to and how much?

Like most thinks with Seagulls its DIY, Its just a way to fill the tank on the move as most of the seagull carbs are not suitable to us a fuel pump or pressured fuel line like modern motors.

The 'kit' I believe, is an extra seagull tank cap, and parts purchased at the marine section of a sporting goods store, or a proper marine store.
Then you need a drill and a tap and die set

The system pictured above is what we used on our 2,000 km Murray trip we were able to run our motors up to 10 hours
without stopping which we did many times. If you plan to run a motor for more than 1 hour regularly I would use this
system we took our boat out the other weekend without the remote tank what a pain having to refuel on the water will
be using the remote tank next time. I used Yamaha fittings but it doesn’t matter what you use a large bulb is easier to
use and buy quality fuel line, one of the boats used a cooking timer on his to remind them to refuel on our boat we waited
for it to splutter got caught out a few times. The only down side was when the tank was full fuel came out the breather.
