hey everyone. im in the last stages of my parts gathering and need to get this problem addressed. i have a custom secondairy fuel rail that fits top feed 1600's and has -6 fittings on both sides. my question is how should i set up the fuel rail to have the right fuel preasure since the stock fpr is in the 2nd rail. do i need a fpr that will fit on one side? what size hose should i run from the 1st rail to the other rail. what size fittings should i buy? i know its alot to ask for but im know nothing of the fuel plumbing biz. thanks

so no one has ever made there own set up that can give me hints or anything like that?

BASTARD

in order to have the correct fuel pressure you will need to install a FPR at the end of the fuel system before it returns to the gas tank... how you set it up the feed portion of the fuel rail can vary... but no matter how you feed the rails the last thing that both rails need to do is go thru a FPR

ok cool, so now i know what goes on the end. does it matter what size hose i use then if im going to use the fpr at the end of the fuel system to get the right preasure.

You'll have to run a SS line from the rail to the regulator unless you screw the regulator directly onto the rail in which case you'll need the correct fitting with the appropriate threads on both sides. Pressure should be around 40psi with vacuum off and pump on.

Most FPR have threading that goes inside of them so look thru the summit or jegs catalogs and select a regulator with the correct inlet threads and you can screw it directly onto the rail. It will eliminate extra SS lines.

DarkKnightFC

OR you can select a fitting that has the 6 female and male whatever on the other side to screw into the regulator. But you will be looking at some issues as far as getting everything to fit in between the mani and firewall. You might end up having to use some SS line anyway.

i dont have a problem with running extra line as long as the pressure stays where it needs to be. thanks for all the info Dark

DarkKnightFC

No problem, you'll have to buy a gauge as well to fit on the FPR but once you do you'll see how easy it is to adjust pressure. You could possibly even get an electrical one and run it into the cockpit.

found this ont that will fit the -6 lines i already have http://store.summitracing.com/partde...5&autoview=sku

****!! sorry about the huge code. trying to make it a link right now.

**edit** nevermind. it is a link

DarkKnightFC

Thats the one I was going to go with originally. It will screw onto your rail but you probably won't have a damn bit of room between it and the firewall. Just depends, but I know its a really tight space. If it doesn't work then you can always just get the right fitting and run a line to it. As for the line it will need to be the same size as the fittings.

yeah i could run a line to about the middle of the fire wall of close to the drivers side and bolt it there and then just run the return line straight down. hell yeah dark. you are my hero right now.

DarkKnightFC

That would probably be the best place. Just look for the 90 degree fittings and you could turn it right off the end of the rail headed towards the regulator, and then straight down to the stock return line. I ended up going a different route once I realized how much the fittings and line cost just to be able to go aftermarket regulator but all in due time I'll have my budget fuel setup.

really? how much was the the lines and fittings?

DarkKnightFC

Just take a look at the fittings at summit or jegs, just depending on who you go with. It can start to get a little out of hand. Some of the fittings are expensive and some aren't, just dependant on what you need. Get a good idea in your head and or draw it out on paper. FC3Spro.com has a really good writeup on the ideal fuel setup.

ok it looks like a $200 job which is a little crazy. but in my mind i was going to use the stock primary rail then run it like the stock system? im starting to think i cant do this.

Dude just get the lines to hose connectors. I have a aftermarket fpr and I'm using rubber lines. The whole thing cost me about $200 for the fpr and the fittings and hose.

heres my set up...

you ran it just like on the fc3spro web site. this is a really good pic of the parrell set up. did you have to modify the primary rail? how much was you set up?

FC3S_nataku

iTrader: (3)

one more thing when you do this you get rid of the stock PD right? thats not going to hurt anything right?

my fuel rail was bored out in the middle and tapped for the 8an fittings, i didnt modify where the injectors go, they are 1600cc as well...all together with my injectors, fuel pump, regulator, gauge, pd, fittings and lines were probably ~$1000. there has always been debate about removing the stock PD, if you are running stainless lines you will need to get rid of it i think, i just bought an aftermarket one because im trying to run 400+ hp and i want to be safe. if you are running a lot of hp it would probably be a good idea to have a PD, just my $.02. read this: http://forum.teamfc3s.org/showthread.php?t=29559
