one more thing to check. when the tank gets to about 1/4 left, is your fuel foaming/bubbling? You might have the screws too tight holding the tank in and not letting the rubber groments absorbe the vibrations.

Thanks for all the help... The problem turned out to be a tuning issue. My high end was too lean and the low end too rich.

I just had the same problem on my TNX Pro Monster Truck ... and the solution was to use a loooonger presure line ... now i have the same engine behaviour during the entire tank ... just a "tad" lean when its almost dry (just the smell of fuel in the tank and fuel mainly on the tubing) but thats normal ...

I have the same issue. I have 5-1/2 inches of line from the tank to the carb. I have a fuel filter. I have not yet replaced the tank. I keep messing with the low and high speed needles, but I'm not getting anywhere. UGH!!!!

I do get smoke coming from my fuel tank when I open it, though.

So, what are the recommended lengths for:
1) Pressure line
2) Feed line?

Thanks.

Talking

The pressure line and the feed line should be within 1/2 an inch length of each other. I find that a slightly longer feed line works well, but you will have to prime fuel into the line before the beast will kick over.

Also, a tip I have found very usefull, is to ensure you allow the petty lid to "SNAP" shut, as if this is not AIRTIGHT, pressure will fail to build inside the tank.
