This day write to you asking for sage advice.
My problem is I have my 87 cougar unable to walk, because they only get 6.58 volts at the fuel pump.
Also tell you to change the pump and filters and tests which were successful.
Thank you very much

you need to trace the wires back to the fuse, and check them along the way....
I just did'it, But i cannot find the problem.
the volt's are insufficient at the entrance to the fuel pump
