Fass lift pump or Fleece in-tank lift pump

[AEV_CUMMINS]

I am leaning towards doing the Fleece in tank lift pump as from my research it seems like it keeps the most ''oem'' style, in the ways that you keep the factory fuel filters, locations, lines and that it is located inside the tank so there should not be any excessive noise from it. All of which from what I understand about the Fass system is essentially an entire replacement including fuel lines and filters, also the possibility of needing a suction tube or something similar which to me just adds more components that could fail or complications. The Fleece says it fuels up to 800hp and as I am only doing a 120hp tune to push my Toyo 37's around and boost fuel economy while cleaning up the engine.. I think it would be more than enough. On the other hand, the benefit of a Fass system would be a customized ''GPH'' to be exactly what I need and the ability to use different fuel filters that are possibly better? Please let me know your guys' thoughts as I do feel out of my element as I have never done this before.

I have a Fleece lift pump in my Titan tank. Works great, no noise, gauge reads fine. No complaints.

Nice, thanks! Could you please tell me the part number just to confirm? I think this is what I will go with

I will need to confirm (aka find the invoice in a stack of receipts on my desk).

I spoke with Fleece a couple weeks ago about there in tank lift pump for a 2022 I have on order, they told me there pump FPE-34562 does not work for the OEM 50 gallon tank but they are working on one for it as the tank is different from the 31 gallon tank. I believe the 50 gallon tank is deeper than the 31 gallon tank so the sending unit float level would be wrong I believe.

But he told me the Fleece FPE-34562 would work fine on a 21-22 2500/3500 with the Titan tank replacement, this is the route I will be going on my 2022 3500 CCSB Bighorn whenever it arrives for the added fuel range. I figured if I'm pulling the tank to replace the pump I might as well do the tank as well.
