2007 Yukon Denali Build (This got outta hand really quick...)

Sorry, I've been terrible about updating this thread... I just looked and it doesn't seem like I took any pictures during this last fuel upgrade. There really isn't much to upgrading the pump. Use the factory bucket and gut the thing, saw off or grind down anything on the inside of the bucket to make as much room for the pumps and fuel volume possible. Drill a hold in the top of the bucket with a step drill for an AN bulkhead, use a 90 degree fitting (or two) off the top and a Y fitting if using dual pumps. Wiring is plug and play with a Racetronix hot wire kit (you can also make your own). They make a kit for single and dual pumps that works great. Run -8AN if you plan to use E85 or are making big power. It's a pretty simple install, if your truck is newer you might have a FPCM that controls the OEM pump voltage, you might need to reprogram it if you plan to keep it.

**I forgot to add that with dual pumps, you should drill some 1/4" holes about halfway up on the front of the bucket to avoid sucking the bucket dry when under 1/2 tank of gas. Also, dump the return using the factory supply directly into the bucket. Make sure you use submersible fuel rated hose in the tank and just zip tie the pumps together. With two pumps and the socks on the bottom, there is really no movement or anywhere for the pumps to go.

Thanks! I will be taking my 2014 Tahoe to the dealer and have them fix the clogged canister/vent so while the tank is down I wanted to upgrade the pump for upcoming blower. I have the 5.3 LMG flex fuel engine.

You may not even need to upgrade depending on what power you'll be making... I put my blower on the stock 6.2L and ran my factory fuel system for awhile. It made 600+ hp on the stock fuel pump and my wasn't a flex fuel pump. Your pump might be just fine unless you plan on a cam and other mods. Just a thought.

Just cam and DOD delete. Shooting for 500 to the wheels.

Something tells me you might be fine without upgrading but not sure which pump came in your truck. I'd get the part number from the AC Delco site and check the flow on that pump. It'll work for your power levels I bet.

How's the truck man? I'm about to button up the performance side of my build in the next few days and reading up on everyone's suspension. Have you made any changes since your last post, still running the QA1 stuff?

Truck is running great... I went through the entire motor while I was rebuilding the transmission. Broke an input shaft right before New Years. Rebuilt the transfer case since it was original. Still running the QA1 double adjustables front and rear. The front springs settled a bit and it's sitting really low. Need to raise it up but I'm getting lighter 20" wheels and drag radials that will be a few inches shorter. Ride's great though, can't wait to get it to the track this spring. Hoping to get in a 10 second quarter mile soon.

I'm too lazy to run back through this whole thread again, what all is done to it again?

Please keep us updated.

If that wasn't enough, I also installed a Mishimoto Radiator (for those wondering it performs way better than the stock one). I got some great pricing by calling direct. I also installed 7 & 9 blade fans from a 2500HD truck.

In addition to all that, I upgraded to a Granatelli 103mm Throttle Body... Too many issues with my Nick Willams and the throttle blade snapping shut from the blower

Very nice build!

How has that throttle body been working? I've been running an LS2 90mm on my Magnusson for a few years without issues but I'm scared to upgrade to a Nick Williams.

Also what do you IATs look like with the chiller? I typically see 10-15* above ambient normal driving and have seen close to 140* after a 1-2-3 gear run.

Lastly why are you sticking with the MAF? I switched to speed density when I first put my blower on and have had no issues with it.

You really should. It’s great stuff.
