My lack of power suddenly returned yesterday but worst than before. The new filter had about 1/4 tank of fuel thru it. Very little was being pumped to the injector pump though. I started pulling things apart, working my way back thru the filter and diaphram pump then found that there was no fuel coming from the tank. Couldn't even blow bubbles back into the tank. Got the tank drain open and had fuel there however. Finally after draining the tank I pulled the 90deg brass fitting that fed the hose and found a worm shaped piece of silicone with one end wedged into the hose fitting really snug. When I removed it I found it shaped exactly like the edge of the fuel sender unit that the dealer had replaced 3years ago.... :) Murphy strikes again!
