does someone mind telling me what these are..i get a buzzing noise from "C" whatever it is when the ignition is on..is that normal? also is "b" the feed to the injectors and "a" the return...i took B off and it kept dripping petrol from the end taht goes into the engine so i thought id check wot it is im actually taking off before going any further.. to test for a faulty pump should i remove B and crank the engine?
