I saw this problem on my girlfriends MGB a couple of years ago. Her dad had
replaced the fuel pump that had gone out with an off-the-shelf fuel pump. It
would do the same thing. Turns out that this little pump (1 1/4" Diam by 4"
length) put out an amazing 26 psi before it will shut off. I still have it
in my spare parts box. I think it was probably designed for fuel injection
system. Before I figured out what was wrong, I went through the needle and
seat thing also. After all it couldn't be the pump, it was brand new! My
advice is check the pressure. Most systems get by nicely on somewhere
between 4 to 6 psi.
