Besides tailpipe grounding, we grounded the engine hood on both sides. We even
went as far as a shielded ignition. Also, coaxial by-pass capacitors on the 12
volt generator. (this is a few years back) The alternator can be troublesome
as well. Installed grounding devices that went in the axel hub caps and
injected a powder that prevented static build up in the tires. Ohoo
yeah,,,ground straps between the chassis and frame (each side). All this to
get the noise floor down for operation on the 40mHz FM band. I would expect
the vehicles of today are noiser with all the computers on board.
Gud Luck.

Ford has stopped doing this as a TSP? It worked great on my 2002 F-150 (for
the fuel pump noise, anyway). Took the overall noise from S9+20 down to
S9. Grounding the tailpipe took the noise down to S6. A few things I've
tried after that haven't helped much. Mostly ignition noise left now.

The Ford fuel pump RFI filter produces mixed results and requires
dropping the tank because the filter is installed right at the pump. A
better way (IMHO) is to cut into the pump wiring at the nearest
connector (about 2 feet from the tank) and installing coaxial type
feedthrough capacitors. You can find more info at
http//www.4x4central.com in the ham radio forum.
