primary injectors fuel leak !! options?
Smells like gas under my hood, upon inspection it looks likea fuel leak around my primaries.
They are stock (s5 tii 550cc) with 120,000kms on them. Just wondering if it may just be o rings or if its a common thing to happen.
Don't know if I should just get another set of 550s or upgrade them to 720/850 cc? (idle problems?
Insight would be apreciated.
Going to tear the upper intake off and investigate further. I"m assuming the walbro 255 didn't help either :P
car is running microtech lt10s, 550 primaries and 800 secondaries. (s5)

STOP WHAT YOU ARE DOING AND DO NOT DRIVE THE CAR!!!!
That being said, it's your pulsation dampener that is leaking. On the S5's its integrated on the primary fuel rail, which is where you are seeing the leak (the PD looks like the "UFO" at the end of your fuel rail). You need to get a new fuel rail in order to replace it. I had the same problem happen when I bought the car, always had a wiff of fuel in the air. Next thing I know I am driving to walmart and it gets bad. Already knowing what it was I went straight home and luckily the car did not catch fire.
If you fix the problem right away your car will not catch fire. The walbro probably made this worse by beating on the worn PD with the higher pressure...
Go to mazdatrix.com for a new one, its going to be pricey.

i knew it was a problem on S4s.... but is it a common problem on s5s?
I'll take off the upper intake and prime the fuel rail and see whats going on. Doesn't look too bad yet, but i definitely won't be driving it anymore :P

How come you need new rails if you wana get a new PD?? I bought a set of s5 tii rails with no FPR and no PD under the impression I would just buy new ones and slap em on, there is no way to put on just a new PD??

you don't need new rails for the PD. and if its not the pd, check all the grommets and orings to see if its leaking, and don't forget, DON"T FORGET to put back the spacer plate on the primary rail.

Oh well I might have s5 rails, I wasn't aware that the FPR and PD are integrated on s5, does it look like s4 rails when the PD and FPR are connected? Becase mine just look like rails, I'll post pictures later today, I figured you could swap the PD and FPR because that's what you have to do if you run JDM rails on a USDM 7, because the fuel flows opposite on JDM rails than USDM

They look fairly different since there are no threaded fittings. And with j-spec rails you don't need to swap the PD and FPR positions (although you probably could with S4s if you really wanted to). Switching the fuel feed and return lines is much simpler. I have S4 J-spec rails on my engine, so my PD is actually on the back of the secondary rail. It actually worked in my favor after the first PD I tried leaked after my first try priming the system. 10 minutes later I had a new PD threaded in without taking anything apart.

Ok I'll try and figure some way to presurize the system, I was only asking to see if there was a known method, and I would hook it to the engine but I'm building the engine piece by piece lol

Hmm well I'll see if that will work, I'll need to hook up the batterey, I'm assuming I'll need the ecu to run the fuel pump right? And I have no fuel injectors any suggested on how to plug the holes in the rails?
