Well, BIG OOOPPPSS. The dealer started to install the 52 gallon tank today and guess what? Turns out this is in fact is the 52 gallon tank for the cab/chassis trucks and it WON'T fit my truck (QC-SB) unless the spare is removed! What really ticks me off, is I originally asked them to put in an Aerotank 60 gallon unit (which drops the spare tire 6") and they suggested the 52 gal unit instead. I SPECIFICALLY asked them if it was a straight replacement and didn't require dropping or removing the spare.

My bad for assuming anyone at a dealership actually knows what they're talking about. My apologies if I led anyone astray with this info. Looks like you will have to go with an in-bed tank or an aftermarket unit like the one from aerotanks.

 

No biggie, I was just curious if it could be done, it would be a nice alternative to having to run a tank in the bed, and take up even more space in a shortbed

I wouldnt mind removing my spare(when I get my next set of tires, 37s, I wont be able to run one in the stock spot anyway)
BUT, I might be better off trying to fab up a tank to go back there...

 

I installed the 51 RDS tank in my 07 ram3500 with 6.7 Diesel. It works great! I leave the valve open all the time and have not had it throw a code yet. I installed a Holley fuel pump to assist the flow but don't need it till the tank is about 1/2 full. After that point it will not siphon (this tank has the connections near the top of the tank for output) I am sure it would work fine if I connected to the drain line. Have run several tanks thru with no issues as of yet.

 

I have the 91 gallon tank/toolbox combo. Won't fit in my short bed, anyone interested?? BTW worked great gravity fed.

 

I did end up getting the tank from Aero tanks that replaces the stock tank. They say it is a 60 gallon tank, but the first time I filled it up I was able to get 65.1 gallons into it. It replaces the stock tank and you end up dropping your spare tire about 6 inches. Works great so far.

 

Will the aerotank work on a 3500 dually long bed?

 

Aero Tanks sells a bunch of different size units to fit any truck. Go to their website at www.aerotanks. com
