2nd Gen Non-Engine/Transmission Fuel tank module/pump

[BMote]

Have just replaced fuel tank module and sending unit. New one has in tank pump. Question is, will this pump work in conjunction with my Fass unit? Will it supply enough volume of fuel? Or just alter system to eliminate the pump. Lift pump on engine block is by-passed, would this in tank pump supply reliable fuel delivery for my engine? Way too many questions to think about. Would appreciate comments.

You need to fill out your signature so we know what truck you have.

No gauges... hmmm. my intank pump I threw away because it was only pumping at 7lbs.
Did you replace the module? Should have gutted the intank pump out of module first and run a draw straw in there.

Your FASS will be much more capable of maintaining acceptable fuel pressure than the stock in tank pump. It is not designed to pull fuel through the in tank pump

The intank pump will flow more than enough for normal use in series with FASS, if you power it. If you don't the FASS will have to work a lot harder to pull fuel thru it.
