Can't seem to find much info on this so I thought I'd ask the forum. I replaced my 11 year old stock fuel pump a while ago with another assembly from Spectra Performance. Since then I can't seem to get the jet pump to work. I get down to about 3/8 of a tank (indicated on my fuel gauge or about 224 miles), and I run out of gas. I pull the pump and the drivers side is empty, and the passenger side is pretty much full. (like 4 or 5 gallons left). I've pulled the pump out several times, checking for possible leaks and/or cracks in tubing, anything. But I see no reason why it shouldn't work. Does anyone know if the o-rings on the quick connect piping are replaceable? or do I have to find another transfer pipe (which I see no part number for on Ford parts web sites or drawings)? Any help, thought or suggestions would be greatly appreciated.
