Now that Losi discontinued the two lst nitro tanks. What are others using for fuel tanks besides the $70 RD Logics aluminum tank? I put in a xxl gas tank and replaced the lines with nitro lines and put a fuel filter clunk in the tank. Truck now seems to run not like it used to, maybe motor dying. Anyone else try the Gas tank with a nitro lst?

Get rid of the filter clunk and run a standard fuel filter inline between tank and carb. The XXL2 GAS tank works fine as it came from the box.

I have a pile of old tanks - mostly 170cc, maybe one spare 220cc tank. The 220cc tanks are around - just have to look-ask around.

Aluminum fuel tank + Nitro fuel is bad karma. Bad bad news there.

The nitro fuel wore out the top seal. It also leans out really bad as the tank empties, worse than a savage. What issues do the aluminum tanks have? I think it's dumb Losi discontinued the tanks, should of at least kept the large one around.'

The o-ring in the cap shrinks with time. Sometimes the screw in the underside of the cap (that retains the o-ring) comes loose. Make sure it's still tight. If you measure the old o-ring and just go a tiny bit larger in diameter or thickness, you're okay. That's what I did - but I think I just used a black rubber o-ring from the plumbing section of the local hardware store.

FWIW - the XXL2 gas tank is a better unit with a better cap. $24 at DollarHobbyz.com

Methanol corrodes aluminum - it's especially bad when you add moisture and nitromethane. Never use an aluminum fuel tank for that reason alone. Besides that, you can't see the fuel level in an aluminum tank.
