Not sure wether I want to go with FASS or AirDog lift pump, but with either one do you have to drop the fuel tank or pull the bed?

With either 150 series pump you have to pull the fuel tank...

With either 100 series pump you can use the stock sender...

But Size is the big issue!

Can't mount a FASS here...

I really, really hate to give a CF link, but this guy did a great job with his Fass vs. AirDog writeup. http://www.cumminsforum.com/forum/3rd-gen-performance-parts-discussion/163170-fass-vs-airdog-you-decide.html

Nice write up... But there is a problem with both setups... Neither one is setup in a protected manner for offroad usage. I got tons of little dents and bings in the bottom of the rocker panels from all the sticks and limbs I ran over. The AirDog if you flat mount to the frame you'll find that the road debris even road gravel will beat the bottom of the filters till they could possibly leak. That why I kept the short bed bracket and mounted behind the transfer case. This way the skid plate protects the filters from damage. Now if your just a city street driver that fine... But offroad use is not exceptable for those mountings. Yes I backed into that location of the first pic...

so the airdog kit comes with the brakect to mount the pump behind the t-case like you have it?

Yes... That is the short box bracket... Or you can get the long box flat mount that looks like typical FASS mount against the frame...

Hey,

That's why I did this:

It sits up an inch or so from the transfer case skid plate!!!
