does look simple. what FPR would you use?

 

oh and another thing I haven't figured out yet is what bucket to use? Will a 99-03 bucket fit in my 04? or is the 04 bucket big enough for a bosch 044 or dual aeromotives?

 

IMO I would not go with a dual pump set up, but thats just me.. I am not sure as far as the buckets, as I have never been into a 04-later truck.. I have not done this yet, but will prob go with a fuel lab FPR..

 

10-4. Thanks for the fast replys. Il look into the 04 bucket a little more.

 

lol.....

 

You can also y it before the rails, feed each rail, then come out of each rail into the fpr, then a return line out of the fpr.

Thats basically the same as a stock returnless setup. Doing it that way could cause it to go lean once it starts using more fuel, it can suck the rails down before the fpr can keep up to the change in fuel demand.

If you do it the way it is in the OP it is always pushing the fuel through the rails first so it shouldnt ever run out of fuel that way, provided the pump and injectors can hang with the power level obviously.

 

Like I said I have heard, saw a few set ups this way and it has been just fine.. Worst case, I figure you can step the FP up. I am going to give it a shot. A million F body guys run this same set up using a stock FPR.. Thats what are gauges are for right??

 

The 04 and up buckets are different than the 03 and down. They're not interchangeable. The 04-up bucket will easily have room for 2 pumps.

 

This is the way to do it. Basically take your original picture, put the FPR in the middle of the front crossover, and feed in the back of the rails with your line split. This will give you the most accurate pressure. Think of it like taking a garden hose, then plug the end. Run the hose straight across your yard, then drill holes in that hose for the length of it. The first hole will always be able to shoot a higher stream. If you tied the plugged end to the front of the hose (so it was a continuous circle) the height of the streams would be much closer to eachother. Your fuel system works the same way. Lots of people run it that way without a problem, but if you really checked it before and after the rails, they would change their system. Also think of it like trying to regulate a river with a dam. The dam is the equivalent to a FPR. You only regulate the water upstream of the dam.

 

Here is a drawing I did of my set up i'm working on. Single Aeromotive 340 in tank, with stock feed line to the rails with 8an hose and fittings. Return will be from the Aeromotive fpr 6an to the tank with a bulkhead on top of the tank. Holes will be drilled in the bucket along the bottom to keep it full. there is a in line fuel filter that will be used right after the feed line and before the y-block.


I had to scale the pic to fit on here so the details in the writing are hard to read. Also it's just a vague layout to get the visual of it. I did it in CAD so I had to scan the drawing then change the files for it.
