I'm considering removing the charcoal canister and using that space and mounting holes for the surge tank. I'm still in planning stages but I'll probably make some kind of shield to protect it from road debris.

I'd like to avoid the setup pictured above since my car must pass tech (and I don't want fuel in the cabin anyway), and I'm wondering where a good place for the reservoir might be.

Bond007, you are not correct, SCCA, NASA, JGTC, and many others routinely have parts of the fuel system in the car. Most require a metal bulkhead(a couple of sheets of aluminum with a piano hinge), but probably half of all production based race cars with fuel cells have the top of the cell in the main compartment.
No one would argue that isolating fuel from the passenger compartment is a good idea, but it is also better protected from major damage in the chassis than out. Take a look at a road race car the next time you are at the track, most likely you will see fuel system components located within the main compartment.
Anyway, not disagreeing with the premise, just pointing out your facts regarding rules are incorrect. Regards, Carl

Most of the cars I have looked over (IT, Showroom stock) don't have the fuel system routed inside the car, but they are closer to a street car than a production class vehicle.
I don't have the whole GCR in memory, but I'll make a point to look through the differences in fuel line stuff between production and IT/Showroom when I have some time.
I still contend that for a street driven car, that you need to keep the fuel out of the passenger compartment, no matter what kind of line it is run in.

NO rubber line, or Hard line(as you see in the Japan magazine, even thougt they are cheap and easy to fab, but during the accident it might got bend or crack)

Not a good thing to have going on inside the car.

Many cars have the stock system in the Car, including the JC Cosmo, the GTR Skyline, The Toyota Mark II (cressida for the states?) some are seperated via bulkheads, some are not. it all depends on how you engineer the thing, not where its located! You could route it anyway you like as long as you do it correctly if memory serves me correctly the Honda civic from 75, all the way to 88~89ish had the fuel lines running under the friggin carpet, on the drivers side for the JDM models, so yeah maybe your fancy nitrile butyl silicone whoopty doopty hose might leak vapors but how about just useing strraight gauge steel fuel tubeing? pipeing?, and custom routeing a steel fuel line?

why doesnt somebody consider the cosmo 3-rotor pump simple install ,clicks right into place ,just like stock
i ran with 2x550cc and 2x1600 with the cosmo pump 20psi boost no problem

SR Ultimate flow test info at 13.2v:
http://maxcooper.com/rx7/parts_info/...exi_bnr32.html
I believe SR is selling a different pump now, but it is probably similar in performance, if not better.

I have a walbro 255lph but with I only have a gt35r , if your going with a R85 kit that is 600+ hp at 25 psi, I would go with the apexi or 2 walbros I doubt one is enough

Yea, I have the ultimate, I beleive it was installed by KD rotary and left me stranded at 15psi. blew the front seals. could not figure out if it shorted or grouunded out but looks like I'm going external.

SR Ultimate failed on me too, in the first 1000 miles.
I now run the Apexi33(?) from the Rx7 Store, rewired for a full 14volts the pump flows a ton. I run just over 40 psi base pressure so when I'm at 19+psi the pump is putting up well over 60 psi!!!!
The Apexi is not a drop in and it makes a hell of a noise at 14 volts.

Previous owner of my car installed a standard pump from a Mercedes CL500 on a TD06-25G setup. These are priced at around US$100. The pump's wired outside the tank and I can't be too bothered to install twin Walbro 255s since the fuel rails are now setup this way. I've seen it hold up to 6 bars on my fuel regulator and I'm getting a new CL500 pump to replace it. In terms of flow, if it's good enough for 5 litres, I'm sure it should be good enough for a single turboed 7.

Holding pressure at idle (if that is how you tested) doesn't tell you anything about how much it can flow at high pressure like it will need to do on boost at high RPM. Forgive me if you did test at high RPM + high boost, but it sounds like you just cranked the FPR at idle to see how high it would go.

You guys want fuel pump info/specs ???????
Look here..............http://www.stealth316.com/2-fuelpumpguide.htm
Here's a list of pumps in order of flow @ 43psi and 13.5 volts:
Mits VR4 -(Denso#195130-0810) = 180 lph / 48 gph
Mits Evo8 -(Denso#195130-3360) = 191 / 51
Mazda RX7-FD -(Denso#195130-0782) = 223 / 59
Nissan 300ZX-Turbo -(Nissan#17042-40P05) = 241 / 64
Mazda Cosmo-20B -(Denso#195130-0771) = 248 / 66
Nissan Skyline R33 -(Nissan# ??? ) = 252 / 66
Walbro GSS 341 -( #341, high press ) = 262 / 69
HKS Skyline R33 -(HKS# 1407-RN019 ) = 268 / 71
Toyota Supra-MKIV -(Denso#195130-1020) = 277 / 73
A'Pexi BNR32 -( #404-A011 ) = 300 / 79
Mostly tested by RC Engineering.
I personally run a Walbro GSS 341 and been very surprised of its flow for its size !!!! I've run 127 mph with it on pump gas on OEM wiring......I've finally re-wired it for constant 14 volts and A/Fs have gone from ~10.8 to 10.5-10.6 across !!!
The Supra pump is also a prefect upgrade for the FD's since it's exactly same size and same connections.
My only issue with the Walbro is fuel starvation under heavy launching in 1st gear with less then a 1/3 of fuel in the tank. 1/2 tank if gas problem is gone.
Hope this helps....

Fuel configuration
Ok boys, I need a setup? Here is what I have.
I bought the car incomplete with these parts. Sard daul pump surge tank, two walboro 255's, all stainless lines#8, an fittings, Sard primary and secondary rails, RC Enigeering 750 pri. 1000cc secondary injectors. I was told that the rails are such high flow that they don't need bigger injectors then that.I find that weird???? The motor is a new street port with a GT 35R. I think it is a 35/40. I may do a GT 40R later so I want to prepare. I plan to run 16 to 20lbs. all the time. This will be primarily a track car. Also going to run Meth inj. I need a set up drawn up for me. I also need a good answer on the surge tank being in the car trunk space or not?
Thanx,
Glen
