I currently installed a Walbro 340 intank and removed the stock pump along with the ATI's inline. I need to know if the 340 alone will provide enough fuel along ATI's FMU for my application? See below.

 

I think the fuel pump will supply your car without and FMU. You may also want to install an Kenny Belle Boost a pump.

 

put the inline back on its just extra insurance man!!! If you have a afpr you can always tune your fuel system that way!! With power adder cars I would always rather have too much gas as not enough. Goo luck man

 

the inline will actually hurt flow.. so leave it out

 

Usually these intake pumps are more geared towards flow and not PSI where as the inlines are geared towards PSI.

We tried using a FMU and a 255 intake pump and it wouldn't build over something like 65psi. Adding a T-Rex (which orginally came in the kit) got it up about 15psi.

As far as using a 7730 (speed density) do a search for speed density and see what i've said about it in the past.

YOu have a good option of switching to a 7749

 

rooster-
you must get the high pressure 255 intank. the trex flows <255lph, its something like 210
