FUEL SYSTEM INFORMATION

1999-2003 4.8, 5.3, 6.0 all had a fuel rail with 3/8" supply line and a 5/16" return line.  The fuel pressure regulator is on the fuel rail, and has a vacuum line to the intake manifold. In 2004, truck engines went to a single 3/8" supply line, with NO RETURN LINE (returnless) except 5.3L L59 Flex Fuel vehicles.  For 2004, Flex fuel engines KEPT the return line, BUT used a fuel pressure regulator with a lower pressure ratting.  2005 5.3L L59 Flex Fuel engines switched to a single 3/8" supply with NO RETURN line in 2005.  Non flex fuel engines, fuel pressure spec is 55 to 62 psi with vacuum line disconnected, fuel pump running.  5.3L Flex Fuel engine 2001-2004, 48-54 psi with vacuum line disconnected, fuel pump running. 2005+ with returnless fuel rail all shared same fuel pressure spec, 55-62 psi.  There is no vacuum reference on these, so fuel pressure should remain constant under all operating conditions.  The computer is programmed differently for fuel flow rate depending on type of fuel rail.[/b]  This is important to know when having a PCM programmed.  (exception: 04 express van and 04 trailblazer/envoy still used return style fuel rail, 05+ single line, retunless rail)

Matt found some severe rear axle truss cracking on the top right side upper link at axle.  Further investigation mandated using the porta ban to remove and rebuild.  the truss isnt trying to rip it self off the axle, but rather the top plate of the 1/4x2x3 box is trying to shear it self in to pieces from the push pull loads from the upper links.  plug welded 3/8" plate top plate with brackets put back on with additional braces is the plan.

front chassis work with removable crossbar and cooler mount finished up last night.

new trans fittings coming in today to resolve drive shaft clearance issues so it should be able to be ripped around the shop lot Saturday. 

coolant leak at water neck needs addressing.  tire carrier work / tins

Thinking of switching to these when my current set of Trepadors are done. First need to see if I'm even worthy to get them haha.

The KR's are not the right tire for us for anything we do.  the Mint maybe but thats all.

KR3's look just like Nittos and Toyos not talking about KR's.

they remind me off the european offroad tires that I've always liked so much with the open shoulders and closer traction pattern in the middle.
