Message Yeah, I knew you’d replaced a lot of stuff. I’ve seen some of your ongoing posts but didn’t really have a definitive answer to help you :-(

I would consider buying some cheap hardline or rubber fuel injection line (hardlines are probably cheaper for the length required) and bypassing the factory lines and see what happens. Don’t spend a lot of time making it a pretty setup, just get it so the car runs and see what happens. Even if you had to (gasp) run the lines through the cabin, out a window, and under the back of the hood into the engine bay. I’m talking bailing wire and ductape test methods here, just to rule out the fuel lines.

When I was troubleshooting that RX-7 I actually had a pickle jar of fuel under the hood, with a line from below the fuel level running to the carb, and another line entering above the fuel level. I ran the line above the fuel level out of the back of the hood, through the driver’s side window and I blew on the line to keep the jar pressurized and get fuel to flow to the carb. My neighbors thought I was an escaped insane asylum inmate, driving around the neighborhood with the black hose running from my mouth to the hood, LOL. Anyway, the setup proved to me that it was a fuel delivery problem and not a carb problem and let me narrow down my search until I figured out the rust in the tank problem.

There are sometimes (always?) a section of plastic tube that is loose inside a new fuel filter. I seem to recall that I usually remove it? Anyway, is there some remote chance that tube is blocking the fuel flow somehow after a while of driving. Yeah, really remote possibility I know.

Mike
