HI,
I am looking at the 50 gallon Titan Tank to replace my OEM fuel tank in my 2012 Short Bed FX4. Is this the biggest OEM replacement tank available or can you add a 40 gallon auxiliary in place of the spare tire in addition to the stock OEM tank/ Thank you

 

I have seen people add the 40 gallon spare tire tank as well and have them feed into each other. The only issue is you need to make space for a second fuel cap, most people put it in the bed.

 

I had a shorty 2001 F250 and installed a 70 gallon OE replacement from somebody. Bought it on line but I'm having a senior moment right now and can't recall the company. It hung down a some but worked great and I did not have to move the spare. Came out of California. Check on google you will find it. Not Titan or Transfer flow. I'll find the brand and put it up in a few minutes.

 

OK, got it. The company is Aero Tank, It was a 55 gallon tank which mounted in the space where the OE ( 28 gallon) was. Check it out,

 

If you are adding this for your towing needs, please consider the amount of weight you will be adding and the drop in your payload carrying ability

I was going to jump on an in-bed 50 gallon addon tank and then started calculating what that extra 5 to 600 lbs was going to do to my SRW GVW !!!

decided that the wife's kidneys required a stop every so often ANYWAY, so wasn't buying anything as far as saved time
