Well do i get a half a told you to futz with the filter? sucks you burned out your pump controller bu am happy you figured out the issue.I finally figured it out this morning. My fuel filter was plugged. Unhooked from the carb to begin draining the tank, and fuel just trickled out. Good pressure directly out of the pump. So I removed the filter and bingo. I took the filter apart early on in this journey, and it looked fine, but apparently the sintered bronze element is all plugged up.
Also managed to burn up my fuel pump controller by placing the diode across the relay coil backwards, shorting the output or that’s what I think happened anyway. So, $280 to replace a $12 filter element. Oh well, it’s finally fixed and I can drive it without fear of getting stranded.
