Upgraded fuel rails / lines. When do i need them?

[slow ride]

I'm just going to mod the stock rail to be dual pass with a single return out to a aftermarket regulator and stock lines. Helps keep the rail balanced at higher flow and the aftermarket regulator can deal with the larger pumps at idle etc.

I ran stock lines to the firewall. Then -6an in parallel to 034 rails with an A1000 fpr. Pretty easy and simple set up.

So i can remove the stock one and install a A1000 FPR before the rails and be fine?

I went lean and burned up an engine at 600whp with a 525 on e85. The factory lines are not up to the task from my experience. It was pretty obvious In my logs the pump couldnt maintain pressure but I killed the motor before I got to upgrading lines.

If I were you I would 100% upgrade the lines.

So i guess this is a MOST then for me.

From the tank to the firewall. More clearly stated: I didn't touch anything from the pump to the firewall.

you have any pictures of your setup?

No, FPR goes after the rails, not before. And you can't use that FPR with stock lines. I ran my own fuel lines from the firewall, to the motor, then back to the firewall.

yeah sry meant after. Can't i make a adapter so i can connect the stock lines on the firewall and after that to AN line and fitting that goes to FPR and rails ( 034, IE, etc ) stock lines should be fine from tank to firewall.

Yes, Sorry I thought you wanted to just swap an A1000 in. I run aeroquip -6an lines. So a line from the firewall that goes under the manifold (heat wrapped). There is a Y under the manifold and both lines poke out be the TB where they meet 034 rails. Once the lines exit the rails they go straight through the firewall (cut 2 holes w/ grommets) and then Y back into 1 where the AC lines used to go through. Then that one line goes to the FPR. After the FPR I have an E% sensor then back to the factory lines at the firewall.

will have to keep this in mind when i get to do my lines.
