Could I get help on how to put together my fuel system? Truck its running great on the street but at the truck it bogs down off the line, I was told that I had put together the fuel system wrong. This is how I have it,



On the driver side of the regulator its the inlet from the fuel pump aeromotive a1000, the bottom its the return to the fuel cell, the other side goes to the back of the driver side fuel rail, then on front the 2 rails are connected from one to the other, and on the back of the passenger fuel rail I have the fuel pressure gauge connected, which the fuel stops there kind of blocking it.

Also I was told that I should connect the vaccum line instead of having it disconnected as I have now.

This is a picture of how the guy told me how to do it. You can't see the back but he told me to put a Y and feed the back of the two fuel rails from the pump then as in the picture.



I hope this will be the way to fix this problem, or could it be that the injectors are overkill, 75lbs RC injectors?

Thanks,

JJ

 

depends on how your injector flow rate is..if you have it for vaccum refrenced and you dont have the vaccum line on it can make it rich..mine was...
heres how my fuel system is ran..the line on bottom is the return line, front line is to the rails, and the line on the passenger side is the feed line

 

I don't know the injector flow rate, but would I have to retune for vaccum refrenced? I don't tune the truck so it hard for me.

I think it was going rich but dum me didn't check the fuel pressure gauge. I tought that with vaccum refrenced the fuel pressure would get higher as it gets boost causing it to be even richer.

 

more than likely the tuner didnt do my tuning on the A/F down at lower rpm's..
