I've bit the bullet and ordered a surge tank, and am kicking around mounting locations on my 2011 Crew Cab Sierra. Crawled underneath the other night to see what I have for room where it will be protected by the frame and body. Surprisingly hard to find 9-12" of vertical clearance on the driver side. Mounting in the bed is not an option.

Where have you mounted yours, any photos, and what would you do different if anything?

 

below the bed?

 

The tank looks like this:

Surprisingly not as much room under the bed as you'd think. I didn't check behind the tank, but between the front of the tank and T case to take advantage of factory routing.

Height is the challenge. By the rear of the Tcase I have roughly 13" of height. The spot under the hood I have 12" if I don't remove/modify the factory tray. The more I got under and looked around this may be the safest spot- it will be away from the ORY, and in front of the driveshaft so as long as the tcase doesn't grenade I'm good I think. I'll have to check behind the tank to see if there's a good spot there. What's another 8 feet of hose...

 

You can mount it horizontal just make sure your return is at the highest point.

 

Wouldn't that essentially reduce the capacity by half?

 

Yes/no
You can put it at an angle but you dont have to mount it vertically.
The stock pump will flow a bunch at very low head pressure.
What pumps are you using in the surge?

 

Stock FF pump to feed the surge tank, 2 AEM 400lph pumps with one hobbes switched. 8an for feeds and returns.

According to deatschwerks calculator I'll only need just over 600lph at WOT..... we'll see.

 

Yea i wouldnt sweat it.
It would take awhile at peak power to even use half of that tank and the factory FF pump would flow plenty.
Mount it on a 30-45* angle to help save space.

 

Sweet-THANKS!

 

There's more room between the bed box and the outside of the bed, in the gas filler area, than you would think.
