Message: [QUOTE="Tree Trimmer, post: 69790, member: 716"] just thinking out loud, but it seems that the longer he drives it, the lower pressure he gets. if the regulator was bad, would the pressure be stupid all the time, instead of just after a drive? if the pump was on the way out, even with good voltage, that would cause the issues he is having. sounds like the longer the pump is working, regardless how hard, the longer the pump is on, the lower the fuel pressure gets. to me that says fuel pump. an electric motor getting hot will do just that. i have a auger on a grain bin does just that. the longer i run it, the slower it augers. shut it off for a bit, picks speed back up. my money's on fuel pump. im not familiar with fuelab pumps, do they have a "reset button" like a regular electric motor, where if it gets so hot or draws to much voltage for some reason it shuts itself off, till it either automatically resets or you manually reset it? or is there no fail safe, and it either works, or kills itself?
