The fuel pump is making a racket and the car wont pull off. It will idle and start but is like a kangaroo when driving When its warm and on the lpg it runs fine. So with the bag of spanners sound from the pump and the running problem its the pump. Ive got a new pump but i cannot get the 2 fuel lines off the old pump. I have a special right angled pinchers to go around the red plastic bit but they wont release. I can push the pipe up and down and its free , but they wont pull off. Obviously i dont want to tug so hard i break them off so any tips would be appreciated. Ive watched a u tube vid on this and it and he says just pinch with fingers and they pull off , but that not happening with me, Any tips would be appreciated
