I drove a Taurus for a few years, and had fuel pump noise too. But the blankers
on my rigs DID cut it out. Are you sure it's getting in via the antenna? Sounds
as if it might be in your audio stages, which would point towards DC power
noise. Oh, one thing I did have to do was ground the exhaust pipe to the frame;
it was conducting noise towards the antenna feedpoint (frame mounted antenna).
I used both a 735 and a 706 and a 290H in the Taurus with no great problems
