could anyone please help.
a guy changed my fuel filter today when i picked car up it was very sluggish. the aa came out and turned a screw under the fuel filter no fuel drained out you could just here air and gurgling. he couldn't find the problem. when he removed the inlet hose it would not start again. when he left i had a look the inlet hose seems not as tight as the outlet hose could it be this. anyway i pushed the hose in out where it was moving and the engine fired up car is running but very underpowered any ideas would be appreciated.
