Fuel pump testing
The pump is a Carter M6907. Street Super pump. Like everything on my car its shelf life got to it before it failed on its own. Between the bad coil and a weak pump it’s been a real challenge to keep this car running.
So I tested the pump and it went as high as 5.5 psi at 1000 rpm and faster. Tried it at cranking rpm. 4.5 psi. Tested it a 3rd time running again. 4.5 psi. After shut down the line pressure bleeds off to zero in less than 5 minutes. So that’s not good. No fuel in the line means extra cranking when cold. And it’s been a real bear to keep running when cold.
I considered rebuilding it but I doubt there’s a kit for it. For another $125 I guess I can just put a new one in and hope it works as advertised.
