TBI Fuel Filter with Carb and Mech Fuel Pump

[GA_TMAC]

Hi Truck Crew From GA

BACKGROUND: Doing a crate motor swap on my 1987 R10 305 / TH400. SBC crate engine has provision for mechanical fuel pump and I have a intake/carb/HEI setup on hand. My current (TBI) tank and sending unit is trashed. I am replacing the tank and sending unit with new units and would like to use a mechanical pump with the carb (meaning no electric fuel pump). I intend to get a "normal" sending unit/pickup for the new tank too.

QUESTION: Can I run a mechanical pump and leave a new TBI style fuel filter (thats on the frame rail for a TBI setup) inline? I would also add a small filter just before entry to the carb fuel inlet.

Leaving the filter would let me make a hard line from the mech pump back to the TBI filter and it would be a solid place to attach the line without using rubber hose. It would also be double insurance for clean fuel.

My concern is that that would be to much "resistance" in the fuel line for the mech pump to overcome (as fuel was being pushed through the TBI filter and not pulled).

Thanks for any thoughts/advice.
