'99 F-150 to Lightning conversion...please help!!
Just wondering if anyone else has run across this same prob. I have a '99 F150 that i dropped a Lightning long block and supercharger in, changed transmission and the main wiring harness. I swapped the stock fuel pump out with a Walbro 255. I also swapped the factory pcm with a lightning pcm. The truck cranks and runs fine, however, my fuel gauge is always reading a quarter of a tank, except when i cut the truck off. Just wondering if it is on the sending unit end or on the gauge end, and what to do to fix...thanks!!
