The idea is something like this :




I don't know how our fuel rails (5.4 3V engine) are mounted.
Is it possible to use a set-up like this ?
In-tank dual pumps going to 2 independent fuel lines, going to 2 high-flow filters, fuel lines after the high-flow filters one going to the right rail and other to the left rail.
Are they totally independent or they are connected one with another ?
Any comment will be trully appreciated.
Thanks.

 

The fuel rails on the 3V 5.4L are connected!just look at the rear of the manifold and you'll see!

 

Thanks for the input man, but i don't have the truck with me now.

 

Bump.

 

I hate to say it but... Trial and Error.

Your system won't work with the factory PCM. The returnless system is very advanced and setup directly towards what is in the truck. But that doesn't even cover the part where you would need two separate fuel rail pressure sensors to work in unison some how.

What i suggest would be to take all the current fuel lines and replace them with a little bit larger lines that are braided stainless. Now datalog the vehicle and watch the FUEL PUMP DUTY CYCLE and INJECTOR DUTY CYCLE. Now if i remember correctly you don't want either of those past 80% (correct me if i am wrong) And if they are you need either more pump or more injector. And if you do ever peak into the 90% range shut down the run and go home to spend more money.

 

I am inclined to forget about 2 independent lines and use one 8AN line taking the fuel from the dual Ford GT pumps to the engine and keep my stock PCM.

 

why didnt you just buy a gt and put the f150 body on that lol
