Re: [T3] fuel pump relay ground

[Toby Erkson <air_cooled_nut@pobox.com>]

<x-flowed>Here's where I have my fuel filter:
http://www.icbm.org/erkson/personal/wheel.jpg
I made a simple L-bracket that a sheet of metal bolts to, to keep the 
filter protected from debris.  It has 2 micron filtration and a spigot 
at the bottom to drain any water that may accumulate.  The filter gets 
changed every 24,000 miles and I'm on my second filter.  It's been on 
the car since before the Gene Berg 2000 Memorial Cruise and not a single 
issue i.e. my baby has done multiple cross-country trips, not just 
little put-puts around town!  Works great with the stock mechanical fuel 
pump as well as an electric pump (my old Holley Red Pump).  Bought mine 
from J.C.Whitney.
