Hey guys,
Im piecing together parts for my project car. Im going to be running a S5 LIM, FD UIM and TB, on a S5 TII block. Im planning on using a microtech ECU...

I have a aeromotive A1000 fuel pump and -10an feed line. Im wondering if there is a fuel pressure regulator that has a -10an inlet -10an outlet and a -8an return.

Do you guys have any recommendations for what fuel rail to run, I would like to get one with -10 an fittings. Sure its a TON of fuel, but at least I won't have problems with the car leaning out. I plan on making 400+ rwhp.

All advice is appreciated,
Thanks!

Why run -10?
That's like enough fuel for over 700hp!

Just get an adapter to neck the -10 outlet to a -8 or even down to a -6.
The -6 is good enough for your needs.

Since you're using the Aeromotive fuel pump, why not run an Aeromotive FPR?

Another question, how much fuel pressure should I be running?

I know the fuel line size is overkill but the fuel that is not used just gets recirculated correct? So why does it matter? At least the car will never run lean.

 

some will tell you that you can never have enough fuel

 

Most people run it at stock pressures...


Right.
The more fuel you circulate, the hotter the fuel gets.
Hot fuel is a bad thing.
All that heated fuel also spews out tons of vapors.
Now, if you tend to run through tankfuls of gasoline in very short time, this is not a problem, but if you don't drive very long very often, then it could possibly turn into a problem.

Sure, it's overkill, but if you like paying $15+ / foot for that -10 AN hose, then go for it!

My original question still stands, any reccomendations for a fuel rail? And I already have the fuel lines and I got a good deal on them thats why im going from there.

Im sure this car is going to just suck the gas down like nuts, and I don't really drive far very often. The car will mostly be used for spirited driving, and lightly raced.

Thanks!

 

Use the stock s4 TII rails. Get some metric adaptors that go to -6, -10, or whatever you want. The stock s4 TII rails can support somewhere around 650bhp. -10 does seem like overkill IMHO. Sure, you arnt going to run lean but you will have to also think about getting nomex sleeves for in the engine bay on the -10. -6 is more than enough to support your goals and it is not really expensive.

 

heres what you need summit got it. AEI-13101 ,2 INLETS PORTS 10AN AND 1 8AN PLUS 1/8 PORT FOR THE FUEL GAGE PERFECT MATCH FOR THE A-1000 FUEL PUMP.

 

You can modify your stock rails or buy kg parts rails. If you want to modify your rails chop off the end of your rails and clean up the cut. buy yourself 4 of these: http://store.summitracing.com/partde...5&autoview=sku
get yourself some flux covered brazing rod and a mapp gas torch. heat it until it is red hot and then burn off the flux on the rod then introduce the rod tothe joint. This only works if the joint is really tight so make sure that the surfaces are close. It is kind of like soldering a piece of copper pipe, it sucks it into the joint. You are supposed to pressure test it with air but i just stuck them on and pressurized my system and checked for leaks. I do not recommend this. since you have a -10 feed line you are going to have to split it into 2 -6 lines and have one go to each rail. the other side of the rails will go to the 2 inlet ports on the fpr. I used an aeromotive a1000-6 bypass fuel pressure regulator i believe. then the outlet on the regulator goes to the return. Check out the parallel fuel system diagram for plumbing questions: http://www.fc3spro.com/TECH/MODS/FUEL/pararail.jpg

I hope this helps, if i get unlazy ill go take a few pictures of my rails.

 

I do not recommend this as all!

Add heat and vibration into the equation, and you're asking for trouble.

S4 rails can use adapter fittings to make this work, or get them welded with aluminum weld ends.
If you wanna mod S5 rails, get them WELDED with steel ends.

Surprised this thread was brought back to life. The setup im planning on running is a baffled tank, to an aeromotive fuel filter, to the A1000, then through a Barry Grant fuel heat sink, to -10an to an aeromotive Y splitter than it splits to 2 -8an feeds going to the true paralell fuel rail setup. 720/1600cc injectors, Aeromotive A1000 rising rate fuel pressure regualtor and a -8an return line. The pump is also going to be controlled by a aeromotive fuel pump controller.

 

So your answer is the 13101, sorry i didnt mean to bring this back that fpr is the one i got, is the perfect match for that fuel pump,.

 

does anyone know a part number for metric to AN adapters that will fit s4 fuel rails using 6 AN lines?? I follow what red-ricer and wackaroo are saying, just dont wanna have to weld anything unless I have to.

Thanks

 

i may be alittle off on my part number but I have used aeromotive 13020 FPR with my a1000. great results with a 720/1600 setup on a haltech. FYI, SX based out of STL is aeromoties old supplier and they make good pieces for pretty bargain prices.

 

Your going to need to add on one more fuel filter in between the fuel pump and the Y splitter. Youll need a 15 micron filter and a 100 micron filter. One before the fuel goes into the pump and one after it goes into the pump. But why not just put the Y splitter to -6 line going into your parallel fuel set up. Although your going -10 to the Y then -8 to the rails, your setback is going to be the rails themselves which flow like -6 line unless your having custom rails made. So either way, your bottlenecking it, just adding on unneccesary costs.

Im running now 38psi fuel pressure and am using the SX external pump and SX FPR, both have been working very good for me.
