Hi, I have a 2004 RAM with a FASS system installed 3 years ago. I had filters changed almost two years ago and wanted to do it myself this time. I followed all instructions and asked questions but now have a problem. After replacing the filters, I bumped the starter a few times and the pump would not load up. I could not get anything with the fuel filter cracked, but when I cracked the separator the pump changed tune, but more like cavitation and then sounded like it was OK. With the filters tightened, I started the engine and it ran, but only for about a minute then quit. I'm concerned that I have air throughout the system. I took the filter cover off at the engine and no fuel was in the canister (I'm not sure that there should be since the FASS system was installed). All I get out of the pump is cavitation. It is worse with I crack the FASS fuel filter, but seems to help when I crack the separator. I need the rig early tomorrow AM. Thanks!
