I just did mine not long ago. It is super easy to install. If you have any mech. skills you will be just fine. Save the $$ and do it yourself.

 

You should have no problem as long as you know what a wrench is. Just be careful with the fuel line clips. Ask me how I know.

 

I second on the fuel clamps. If your break the connector tube the the in-tank basket, be ready to drop the tank and another $360 for a new basket. The install overall is easy and straight forward. It's easier to get to those clamps with the exhaust out, so hopefully you are in the process of doing that.

 

maybe this will help?

save your money, its not that hard

 

Save your money. Not hard at all. I recently did mine. Just follow the directions. Make sure you use enough thread tape on the threads it tells you to as well. Ask me how I know

 

it takes 2 hours to install one

 

Damn 400 sounds steep to me. It was 20 degrees here and I don't have a garage so I took mine to a friends shop. 400 bucks, did my exhaust, down pipe, lift pump, inspection through 2016
The parts sat in my house for 2 weeks I couldn't wait for warmer weather haha

 

I want to pick up a transfer flow 60 gallon midship and add it to my FASS150 thats on order lol. Do it all in 1 go ahead

 

I installed my Fass titainium 150 on the ground as well. Like everyone says hardest part is that fuel line disconnect, I fought with mine for awhile before I got it.

 

Is there a special tool to remove the fuel line from the tank and/or just in a real inaccessible location?

 

this line?

 

I don't know, I haven't been under there to scout it out yet, but if that's the line I need to disconnect for a lift pump, then yes.

 

I used a flat head screw driver. I found this on Amazon:
