engine stall w/ low fuel
07 FLHRI
Well; in regards to Road king stalling problem;, I replaced the existing shot exhaust baffle w/newer design for my Supertrapp 2-1. Had the Powercommander updated and repaired by dynojet w/download for upgrades. Well; bike still soon stalled out on acceleration, but would start right up,but crawl home. I filled tank w/fuel, and problem was gone, and ran perfectly. The only components I would think to inspect and/or replace now, would be the lower fuel hose from filter to lower tank fitting, and/or the fuel pump. I've already replaced the idle actuator, short fuel line in tank (from regulator to pump), filter and regulator.
Any suggestions what to replace or test?
Thanks;

How empty was the tank? If you went more than 20 miles or so after the light came on before refilling, the symptoms you describe would occur.
If the tank was around half full, I would suspect a pinhole leak in the fuel pick-up line.

Thanks for reply. The lower line is the next replacement. The tank was at least past reserve to quarter tank. If replacement doesn't fix, I can use either new or modify existing fuel line to test operation of pump output. What pressure out of pump am I looking for?
Thanks again;

Hi All;
Well I've so far replaced both lower and upper lines, regulator and filter. still same problem. Crimp clamps on tight. Mid red bar to 1/4 tank on gauge runs fine@ idle. Run hard 2 miles, and shuts down. Starts back up but keeps shutting down shortly after start-up, repeats each 1/4 mile, but still runs great @idle. put just over 1/4 tank of fuel in tank, no problem; runs great at any rpm's. Problem seems to be in tank, what next?
