Has any of you replaced your fuel tank to a larger one? I think the 22 gal. is to small. How big did you go? Any pros/cons?

22 Gallon? I have an '04 Crew Cab w/ a 34 gallon tank stock. I thought all diesels were 34 gallon. I also "home made" a 65+ gallon tank to fit under my tool box in the bed of the truck . I've got about 100 gallons a shot that I'm good to go for, it only cost about $175 for the bed tank since I welded it up myself including the price of the transfer valve into my main tank. Merchant Automotive has 54 gallon tanks that will fit into a crew cab if you're looking to swap out the stock tank.

My '06 CCSB is 26 gallon which is annoyingly small. Titan has a larger tank, 45 gal I think, that is a direct replacement for the CCSB stocker and a larger one for the long bed. I'm sure there are other manufacturers that make replacement tanks.

I got a quote from a Tranfer-Flow dealer for their 45 gal oem replacement tank. Installed price is $1200.00. Now if I can just figure out how to hide that much money from the wife? :D

any downside to swapping in one of these transfer flow tanks other then spending more money at fill up? do the gauges like fuel level and the range monitor in the dic function properly?

I've had the transfer flow 46 gal tank for about 8 months now. The only difference is that the DIC still calculates "distance to empty/miles left" based on a 26 gal tank.
Transfer flow told me I had 40 gals usable in the new tank so I just go by the guage and the DIC's "fuel used" numbers.
IMHO, the larger tank is well worth the $$$$.

Love my Transfer Flow 45 gal replacement tank. Fuel guage is accurate, just slower, 'range' is now useless, 'fuel used' is all I look at. Well worth the money, I'd do it all over again.

Couldn't the Dealer reprogram the BCM so the DIC would reflect the new larger tank size? Doesn't the 1-ton have a larger tank? I would think the electronics would be the same and only the programing would be different.

That is way too much for a Transfer Flow tank. I think retail they are 600 something, can't remember exactly what I paid for mine. They are a piece of cake to install. Get a buddy and do it yourself. Need a couple of floor jacks and a couple of jack stands. NO PROBLEMA In fact I'm in Boise right now swapping engine and transmissions in my crew cab. We took mine out today and I sold it for $300. Gave the guy a great deal because we are using his shop. :D

Just looked up the prices and the retail on the one I got for my LB7 is now like $777.00 I know with shipping mine was less then $700. I did not pay full retail however. Prices have gone up. But save yourself a bunch of money and install it yourself.

Just noticed something, says the LB7 tanks are different from the LLY's and LBZ's anyone know what the difference is? I was selling my LB7 tank to a guy with a LBZ but it appears it may not fit, what are the differences?:confused:

We used the sending unit out of the old tank though so I don't think that is the difference. Will have to ck with the company on monday. It would have to be the weekend. Damn!!!

Thanks for the insight Subman. The break down is $765/tank, $100/shipping and $315 for install. How long should it take to install the tank?

With the help of a buddy 2 hours tops. Make sure the fuel tank is almost empty.

I replaced my stock tank in 2004 with a Titan 53 gallon tank. In the time that has passed they have improved it greatly so I ordered a replacement (not to mention the old one was installed horribly crimping the return fuel line and began to cut in on the brake line. It will be installed Tuesday and will let you know what the results are.
