My question is this. If I just replace the fuel pump would the new one
be quiet you think? I'm guessing that the fuel pump is originally the
one that came with the truck.

IIRC Ford has had that problem almost forever since the advent of the
electric in-tank fuel-pump.

I'm kind of leaning towards bad ground. Run the CB's negative to something
well-grounded like a bolt on the frame if possible. Did that with a 2001
Ford Ranger my roommate used to have and it got rid of the noise.

Another possibility if the truck turns out to have poor grounding in general
(such as my mid-90's Kia Sportage) is go with the best ground you can
reasonably get to and use something like the Ranger RCI 2950 and run it
with ANL/NB turned on and get good at reflexively adjusting the RF gain.

And connect the chassis to the frame to the battery...

Those ground straps and their connections go bad!

Any sideband radio has better filters then an AM only radio.

Hello All:

Yeah Scott is right here. In my Ford Truck I connected the Battery
Ground to the fender, then ran a braid wire to the firewall, and then to
the Hood. That made a big difference, in reducing RF Hash Noises from
the Ignition System.

Jay, Mr. Faraday would be proud of you.

Hello TE:

I don't think Mr. Faraday had anything to do with it. Is that guy on
channel 12, and goes by Fright Hauler? Has a Cobra 148 and Texas Star
500, and has duel whip antennas?!?!?!

Well anyway grounding the fender, firewall, and hood was a significant
improvement in reducing the ignition noise. I also ran new shielded
wiring for the Ignition Modular, and that didn't help as much. Oh yeah I
also added on copper tape (from the TRW Swap Meet) applied a 1/2 inch
width of the copper tape every 3 to 4 inches on the center distributor
wire, this was also a big help.

I have a Motorola Radio in the Truck, and its has a really neat noise
canceling circuit in it.

And another noise reduction idea, would be a Clear Speech External
Speaker with DSP Noise Reduction. Yeahs its 200 dollars, but if ya want
to play ya gotto pay.

I know guys fight the noise coming from a noise fuel pump in the plastic
gas tank. I would wrap the plastic tank with wire, and add in a power
lead filter.

Jay in the Great Mojave Desert, ....just down the road ah ways from the
fillin station.

Just get a different truck. Then you won't have to deal with the
bass-ackwards electrical system, the characteristic cancer above the
fender wells, rebuilding the CV joints on the dual I-beams (a major
PITA), or that annoying and mysterious 'clunk' that sometimes appears
after 100k or so.

I'm not convinced either vehicle mentioned (mine or my former roommate's)
ever had a good ground to start with.

general (such as my mid-90's Kia Sportage) is go with the best ground you
can reasonably get to and use something like the Ranger RCI 2950 and run

I question that assertion. I had been running a detachable-face Midland job
that had sideband and that thing was noisy as all get-go on that.
