Here goes. I purchased an 86 fj60 with a howell fuel injection system installed on a 5.7L Chevy. I have very little history to go off of. I am having problems with intermittent stalling. My gut feeling is that the delivery and return hoses may be backwards. Does anyone have a diagram of the fuel tank, that may shed a little light if I am barking up the wrong tree or may be on to something. Yesterday when it stalled I heard a gurgling noise in the fuel lines. There did not seem to be very excessive pressure when I released the fuel cap. One little tidbit of info I recieved from the previous owner was that when the aftermarket fuel gauge reached 1/4 of a tank, it will run out of gas. These are leading me to believe that something is funked up. Any Ideas? Diagrams of proper connections off of a factory tank. Thank you all.
