Hey guys. Im trying to plan out my fuel system. Setup will be a 6.0 with a t7875 with the holley dominator pump, victor junior, edelbrock rails, and 80lb injectors. I see lots of guys going to a y block. then lines to each rail. the cross over or lines to the fpr. Other guys are going to one rail then cross over, then the fpr mounted on the rail. The one feed line would be the easiest. Is there anyone that has real world data to show that running the y block is needed? I wouldnt think the first set of injectors could use that much fuel to starve the other rails. I see guys making huge power on stock rails even.

Stock rails kinda supply through the center of both rails, for the extra $60 split to both rails and know you wont blow it up from fuel starvation

I would like to have the fpr on the back side of the motor. I want to be nhra certified so I can't put it on the firewall. I would have to run the lines under the intake to the front, to mount the fpr on the back. I dont like my fresh fuel lines sitting on the hot intake. But also dont like the idea of the return line draped around the intake either. Do you have a pic of your set up? Thanks!

Two of my friends have it this way. Feed into the bottom of FPR on the shock tower. One out port goes to one rail, the other out the the other rail. The y the returns to one line back.

Thats how I set it up on a carb but no return. I thought the fpr has 2 ins and 1 return? Not 2 outs and 1 in.

Depends on the regulator!

Is there an advantage to one or the other? Either having them in or having both out?

im running stock truck rails on my setup.my tuner said hes done it builds with dozens of setups with stock rails close to 1000rwhp.so figured mine should be fine since i wont be trying to push that much power.

ive already got the the rails and set up. not going to change out to stock. want to set up what I got. I just want to do it right, once. lol

MY car that im building right now has the feed line going into one side of the fpr then comes out the other side to a y block that goes to both rails, the front of the rails just cross over to each other.
the single return out of the bottom of fpr to the tank.
the way magnafuel told me to do the system was from the pump to a y block to both rails then out of both rails to both sides of the fpr out the bottom return.
the second method takes more line but really all and all the best set up

Thank you 9sec. Thats the kind of info I was looking for. OLDGEASER also had the same info with Aeromotive fpr. Thats what the site recommends. Thats how I'm going to do mine. If thats how the manufacturer wants it, who am I tell tell them any different. lol Now I just need to see more setups. Has anyone seen the brackets that mount the fpr on the front of the intake? Then the return runs underneath it?

IF you are using a factory intake the return will not fit under it, just make a bracket to mount the fpr, 18gage metal and a cut off wheel. you will have $3 in it

its a victor jr. what are they bolting it to though?

IN your case I would go to one of the front intake bolts take a pic of your intake on the car and post it to see what you have to work with

chub406

fair enough. I wont be able to take a pic for about 2 weeks. lol wanting to roder everything. Im going to feed each rail separately. Thanks!
