Today I changed out the fuel filter, once it was all back together I loosened off the bleed screw and started priming the pump.
I reckon I pumped for around 20mins and no sign of fuel. I then pulled off the filter and checked all the o rings and seals and they seemed good. (Small dent on the filter from when I dropped it but is no around the seal.
Started pumping again, still no sign of fuel. Any help would be appreciated
