ts
a tight fit to squeeze a filter wrench around the fuel filter with the
newer longer filters. GM designed a step in the bottom of the can to
help with the problem, but its still very tight, especially with the
wires routed close to it.
After
being frustrated with this, We developed a rather simple solution to
the problem, a 3/8" thick aluminum spacer to move the filter head away
from the valve cover. This is enough room to make getting a filter
wrench in there a lot easier, but not enough that it makes it tough to
get the filter out of the engine bay. We include two bolts that are
longer to support use of the spacer. Install is very easy. Simply take
out the two bolts that hold the filter head to the support bracket and
install spacer and longer bolts. No fuel lines or wires need to be
moved or extended.
Fits all year Duramax engines '01-'10
