What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Rocket Man]

For what it's worth mine is a 2005 flex fuel and does not have a separate FPR or a (serviceable) fuel filter.

Well. I wonder if there’s a way to find out from the RPO codes?

Strange, my FPR is integrated into my fuel pump and is nothing like what's shown in the video. In older GMT800's, the FPR was located on the fuel rail close to the firewall and was easy to access and replace. I had to replace my fuel pump around 120k miles because the FPR was failing, and since it was built into the fuel pump assembly I didn't have a choice but to replace the whole thing.

In 2004 or 2005 GM went from return to return-less system. It depends on the production year of your rig. With the reurnless system they also eliminated a fuel filter under the belly of the truck, and change fuel injector flow map.

In return system, the flow numbers are constant regardless the intake manifold vacuum, and the fuel regulator makes necessary adjustments (that's why it has a vacuum hose from the intake manifold).

In returnless system, the regulator is too far away in the fuel tank to route a vacuum line there. So, the calibaration in the PCM now has different flow rates for different vacuum ##:

This is mostly correct, with the exception of the 2004 Flex Fuel trucks. It's dependent on your model year AND if Flex Fuel or not.

From a post at ls1tech.com (https://ls1tech.com/forums/conversi...ck-fuel-pressure-regulators.html#post16979237).

"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, All engines went to a single 3/8" supply line, with no return (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 2004 and back, 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. This is important to know when having a PCM programmed."

During the holidays and on vacation one of neighbors is a mechanic. I had him change out the front sway bar bushings, all 4 control arms and most steering components. I used all oem GM parts. I painted all parts black prior to getting the work done. SUV rides like new now.

Nice. Perfect timing.

I painted some panels and my doors to match my new interior. Slow process but im getting it done.

Please post up more pictures of the interior, that new interior looks pimp!!

Did you stain the seat belts? Are you using the 03-06 second roll bucket seats?

How did you prep the plastic, and what did you use to paint/dye the interior plastics? Any prior experience with said product?

One place to shop for plastic coatings is materials for motorcycle bodywork repair & paint.....

I'm just interested in the name of the product, along with the process he used. I'd assume it was an SEM product.
