Default Does it matter where the Regulater goes?

Usually I see them inbetween the rails on the front. But does it matter if it is there or on the return line?

How do you plumb your fuel?

I was thinking connecting the front and rear fuel rails with a T. Have the fuel go in the rear at the T and exit the front T where the 1:1 regulater is.


Good Bad???

That is the way I plan on doing it as well as the top mount supercharger is in the way.

that is essentially how I did mine. I instead used a Y fitting (not a T fitting) and supply the fuel to the back of the rails. Front of the rails then go into 2 separate ports of the regulator (my regulator acts as the second "T" in your case)

you are in good shape long as you put the regulator after the rails, and the general idea is the closer the better.

on my car i go in one rail, cross over to the other rail at the front, come out the back of the other rail go through the regulator and out

the fittings and lines around the rails are expensive enough without me buying double

I was thinking that a T might help keep the preasure drop more even.

Tees hurt the fuel flow a lot and should be avoid at all costs.

So do you guys feed both rails individually or just one rail.

I've seen several like poncho's but are both rails feed on the back or is one feed and one capped.

I'm plumbing mine right now. How I'm going to set it up is to have the feed come in on the driver's side. It attaches to the front of the driver's side rail. There's a crossover between the rails on the back. I then have a hose coming off of the front of the passenger side rail that runs to my regulator. The return then goes from the regulator back to the tank. I'm just plugging the other port on the regulator.

So, the fuel comes in the driver's side rail, runs through that rail, crosses over to the passenger side rail, then out to the regulator and back to the tank. Pressure is regulated after both rails.

I have a Y-block at the rear that feeds both rails.
