Default Engine dies when 1/4" fuel left in tank.

Starting yesterday, my engine started dying when it gets down to about a 1/4" of fuel left in it. I drove it today just to see this again and it's really consistent.

It's always right at that level and if I keep the fueling it up and not letting it get down that low, it doesn't die.

It fires right up and runs good even at that level without refueling.

Is there something there that needs to be cleaned or flushed?

It's an OFNA LX2 with a Hyper .21 8 port.

The fuel I've been running and just finished the whole gallon today is Odonnels 20%.

I just bought it less than a month ago but I think it's old and maybe that's why I'm getting what I'm getting if not a tank/filter issue. I don't use filters any more, just the one that's in the tank.

Check your pressure lines and clean out your pipe. It sounds like your tank is not getting enough pressure.

you can try blowing the pressure line and check if the fuel is coming out when the fuel is that low. You can even test it with water, but make sure you clean it with fuel first before running again.

Could try replacing or if possible tightning the oring in the lid of the tank probably just not getting a good seal

Air leak… most likely the tank.

I experienced the same thing a month ago with an Ofna Hyper 7. I had an air leak at the tank lid. I tightened up the screw under the cap, putting a little more pressure on the O-ring, which solved the problem. I also shortened the pressure line from the pipe to the tank. Thanks to the contributors in this forum who helped troubleshoot/resolve the problem
