Pull the carpet up inside the vehicle above the fuel tank and see if
there's an access plate to get to the pump..

Some cars have one.

I've got a Mazda Tribute (near replica of the Ford Escape) and have the
dreaded RFI from the electric fuel pump. I've done a ton of research
on the Internet and determined that the most popular option for
resolving the issue is to install a RFI filter on the pump. This
involves dropping the tank, which is beyond my capability. So, to do
the install will involve a trip to the dealership, costing around $200
for parts/installation.

I've also seen a homebrew ferrite filter that can be installed at the
power lead for the fuel pump, which is an option.

But, I did see one posting where a guy resolved the problem by
upgrading to a K40 antenna, which he said filtered the RFI. So, I'm
wondering if anyone has had success eliminating fuel pump RFI with a
good antenna? I'm willing to give that a try, but it will probably
involve ordering one, so if there's only a small chance it will work
I'll probably skip this option and go straight for the filter.
Thoughts?
