Status: offline 		wow.  the purpose of that is to pressurize the fuel tank, not suck fuel from it.  how can it be running backwards?  i'd love to hear what people say.

Status: offline 		If the fuel is pumping from the tank to the exhaust it wouldnt run, you are running super rich and some fuel is gathering in the pressure line, remember the exhaust doesnt pump air into the tank as in volume, it just pressurizes the tank so the only movement of air is as the fuel drops. You running way to rich, which explains the fuel in the pressure line and the poor fuel mileage. lean it out!

You shouldn't have to modify a product for it to work as intended. were the lines just hooked up backwards, and you drilled another hole (probably ruining a perfectly fine fule tank)when all you had to do was hook them up properly?

Status: offline 		 well you have here the most interesting problem, like water running uphill.  i guess it's running so rich yod mistake unburned fuel from the motor for fuel from the tank; as people said.  SO did you try running it leaner?

No one can tell you the best setting for your 4tec. its different with everyone,  I tune to the sound of my motor, but its took me many years to do that....alot of guys get a infared temp gun...or get a radar gun..
