I just recently added a Fass 95gph lift pump and saw where a guy added a sump to his tank he claims it helps deliver fuel and helps with fuel levels under a 1/4 tank and I'm wanting to know if this would be a waste of money or is it actually a logical and useful performance add it really doesnt seem to costly but looks like you have to drill a hole in the tank for installation
If you end up having 1/4 tank issues then get one. If not i i would not worry with it. My personal trucks have never had one and ive never had an issue running them to lower than a 1/4 tank and parking on hills.
I installed mine back in January and usually dont let the truck get below half tank. But I have ran it down to around 1/8 tank a couple times just to see if I would have issues and I didnt.
I used the newer style fass with the draw straw that gets installed in the top of the fuel module in the tank.
You shouldn't need one with 95, it's normally the 150 and up that need a sump. If the pump is already installed and you aren't having issues then I would leave it alone.
I concur with all the above, my FASS 95 has never caused that issue. That coupled with I really don't want to cut a hole in the bottom my fuel tank. It just seems like another potential problem to me.
