Default What to do for more fuel capacity?

I'm considering adding external fuel filters (maybee even 2) just to get more milage between fuel ups. Any sugestions on which filters hold the most and how to plum in 2?

You can add fuel filters (without the filters) and fuel line for more capacity.

You can also heat up the sides of your tank and enlarge it by expanding/pushing the sides out from the inside. Kinda of a PITA but works.

You can also get better fuel mileage by taming down your throttle finger

Having an engine that is good on fuel is the number one thing to do. Extra fuel line,fuel filters, or taking the restrictor out of your fuel tank don't really give you any significant increase in runtime, maybe a minute.

Yeah but if you have a $200 motor, all those things are better options than buying a $400 motor and playing with an assortment of $100 pipes
And even then you may only pick up a minute after spending hundreds of dollars

True, but I have a feeling that Gwoodrc might only have a 7 min motor hence the reason he's looking for some advice on gaining runtime.

Yes I had a Ninja (last years, not the new one) in a durango and our track requires alot of wide open throttle so its hard to get fuel milage. The motor was about on its last leg anyway, so after tonights race I decided to retire it for a freshen up with a speed piston and sleeve hopefuly will make it more efeciant. But I also know that the Durango doesnt have a large tank like some other manufactures that you can take the spacer out of for 15-20 min club races where nobodies checking tanks, so I was looking for as much extra as I could find to possibly add a minute of runtime. But now I am gonna put my other motor on (werks B6) that I know gets better milage while i'm freshening up the Ninja!

Default tough question....

I've had most Novarossi engines and every one gets the same mileage. It must be more to do with my driving style and the car, even between my two cars i don't notice any difference, so you could limit the throttle travel a little bit, or run the engine a bit leaner, try a different fuel, but that's all I can think of. even pipes don't really make much difference, but most swear by the 9901 on a nova. Monty's extreme x7 seemed to do pretty good on fuel, it's cool to see such a powerhouse of an engine avoid using more fuel...

Adding too much fuel line and extra filters seems to only cause tuning issues, but hey, that big ol kyosho filter can't hurt runtime...

Many tanks are under capacity. I add fuel filters to get the tank and lint to capacity. No arisen makes a large fuel filter that adds 2.3cc. My fav was the odonnel filters but they don't make them anymore.

Yup ^^.
+Gass cooler.
Longer fule line.or add filters as you mentioned.
Tuning.
Clutch setup.
and an easy throttle finger...

1+ minute of extra run time is pretty much equal to an extra lap on the track.

Too many fuel filters can restrict fuel flow, I would just suggest tapping the throttle

Was wondering about this too.

You said you are in a Durango, which is probably under the 125cc? First thing I would do is measure out 125cc of nitro and dump it into your tank (empty) and see where you're at.

That said, nothing will beat fuel mileage like properly tuning your engine.
