I have a '69 MGB Roadster project car that I am slowly restoring. The fuel pump makes an awful racket (tappity-tappity-tappity) constantlyand I would like it to stop. The car runs nicely and there doesn't seem to be a problem with fuel delivery. From what I have gathered, it should tap a little when the ignition is initially turned on but should then stop. I have seen postings that mention the "reassuring tap" of the fuel pump. Does this refer to the initial power-up or is my constant tapping normal and if so how do I make it stop?
