My mechanic wants me to get a FPR for my car. So which one should I get? A rising rate one sound good? If anyone knows where to get the best deal please let me know. Thanks.

second one down (rising rate)

 

Why?

 

Because I have ALOT of fuel and not enough to tune it with.

 

What exactly do you mean by a lot of fuel? Pump? Injectors?

 

Get an Aeromotive or SX FPR... BOth have a 1:1 rise under boost and both are good units.

You can Get the Aeromotive for 130 bucks from suprastore.com but you have to get -an fittings for it. (i have it.. summit sells the fittings you'll need a 6-an port plug (2.98), two 6-an- flare unions (2@2.95) and a pack of 6-an o-rings (4.95)

Rx7store sells the SX and for around 170 and i think it comes with the fittings

You will either have to replace your stock Secondary fuel rail with an aftermarket unit or cut the FPR off and drill and tap it for a new fitting to attach the FPR

 

Thanks alot. I'll prolly go for the Aeromotive.

 

What about this one?

Or maybe this one?

The thing is I want to order everything right now. Not get the FPR and need some fitting or something and not be able to install it. If it has a -6 return and a -10 inlet what fittings do I need? Is there one where I won't need any extra fittings or no?

 

-10 inlets are like freakin funny car fuel system.. TOO BIG...

if you go to www.rx7store.net choose the -6an option, it comes with the fittings....

http://www.rx7store.net/product.asp?0=211&1=262&3=319

You will still need fuel line and -6an hose ends.....

 

TO get the aeromotive with -6 an ports, and the fittings... here are the summit part numbers...

AEI-13109 (-6an port FP regulator) $131.95
EAR-981506 (Earl's -6an Union for ports on FPR) 2.95 each (need 2)
EAR-581406 (earl's 6-an port plug) 3.75
EAR-176006 (O-Rings for -6 unions Pack of 10) 4.99

This will set up the FPR for use with -6an SS braided hose...

Now... What kinf od fuel rail do you have?????

 

if you look on reteds site then it shows just about all the info needed to run s4 fuel rails in a parrallel -6 an setup. thats what i have going to a aeromotive fpr. as for fuel line and what not just go with the aeromotive socketless line. basically looks like plain rubber but is alot better and cheaper than the ss. i got the ss lines for oil and everything but the socektless line works great for fuel.

 

I have the stock rails right now so I'll have to tap into them, right? I'm actually going to go with a Mallory FPR that is rising rate and adjustable up to 100psi and is only $100 locally.

 

s5 rails are junk. i upgraded to s4 rails so i could get the threaded ends. i got all the part numbers and everything outta this forum. search for reteds parrallel fuel. this is basically wqhat i used http://fc3spro.com/TECH/MODS/FUEL/fsystem.htm
and this is what i used

Rising-rate fuel pressure regulators are just a crude band-aid for under-sized injectors. If you have injectors suitable for your mods then you should use a linear-rate regulator.

Note that it's the pump that provides the pressure not the reg. Just because the reg says 100psi doesn't mean you'll be able to get near that.

 

Actually its not a rising rate. I believe its a 1:1. My setup is4x720cc injectors, a walbro pump, s-afc, and fcd. I have S4 rails and am replacing my FPR now. I also ditched the damper.
