you might have a cracked fuel tank causing air to get into the tank while your priming it..what kind of vehicle do you have?

ok, well double check the fuel tank for an air leak.. you may wanna pull the tank out and water check it by blowing into it while its under the water..just take the tank submerse it in water, plug up the feed tube and blow through the backpressure tube which hooks to the exhaust and see if you have any air bubbles coming from the tank..if you get alittle from the fuel cap then replace the 0-ring on it..and while blowing air through see if the tank bubble from any part of the tank..

Might be some leftover stuff from making the tank in one of the nipples.

You'd be surprised how much crap gets left behind during manufacturing. Not just on these rc car parts, but on anything.

yes, check the opening behind the fuel feed nipple, take it out and blow thru the pressure line. see if it flows freely
