Bubble in my Fuel line

[Joehpi1]

I kinda have troube with my HPI RS3 4. When I was trying to turn it on i see bubbles in the fuel line . How can I correct this .

Blow into your exhaust stinger until all the bubles are gone. Its not usually a big deal, once you get it running the air bubbles will go away.

Its usually no big deal. Sometimes, however, there may be a small crack in the tank or fuel lines causing a leak in the system, therefor putting bubbles in your fuel line. Sometimes, this does cause irratic tuning, and much frustration!

those bubbles are nothing really. Just check if they are still there when running. My engine does that when starting, but then goes away when started... it is all about how you prime the engine.

try removing the fuel line from the carb, pinch it, then turn the motor over with your finger over the exhaust.

If you still have air, then something is leaking.

FYI: if your fuel cell has a primer, this could cause it too. they tend to leak over time.
