t-maxx fuel system

[hotwheel_2000]

Dose anyone know how do stop the cap on a tmaxx fuel tank from leaking. Because of the leak there was not enough backpressure. Before I blew my crank I had my HSN 3 turns out and geting great performance when break-in settings are at only 2 1/2 turns out. Can an air leak in an engine cause the it to run lean?

having your cap on your tank leak air can defininitely blow yoru motor.It will cause it to run really lean!!!!!

they say before your motor blows it will run like a champ...lol:D

you should be able to adjust the cap with the phillips scredriver.Loosen the rubber gasket and see if that helps.

"The last thing that we'll check before heading out to break-in the engine is the seal between the fuel cap and the tank. This is adjustable with a 2.5 hex wrench. Your lid may not need adjustment, but it's a good thing to check anyway. The orange o-ring that seals the tank should fit snugly into the filler neck of the tank.

It should also fit all the way down into the filler neck.If the cap closes very easily with out any tension between the o-ring and the filler neck, then the o-ring is set too loose. Turn the adjustment screw clock-wise to tighten. This will spread out the o-ring providing a tighter fit. The opposite is needed if the cap will not retract all the way back into the filler neck."

I must have the older tank because mine dosent have the orange O-ring. Is it posable to just buy the O-ring or do you have to buy the whole tank

Have you called traxxas on your problem? Do you have a new or old TMaxx? They have great support.

You can also get a new O ring from your Hardware store bring in your old one and I can bet they will have on that is the same size.
