Hi guys

So it's pretty apparent having a fuel smell coming from the rear of the car. Car is in garage, and when I stick my head near my right rear wheel well, I can smell fuel. I can also smell fuel coming from the exhaust, mind you, the car is parked and been there for hours. Is this normal?!

The smell isn't coming directly from the fuel tank filler area... more of the wheel well area...

The non-smart way is to light a match and try and source the leak?:P I'm trying to avoid this method.... any ideas?

is it the wheel arch on the side that the filler cap is on? it could be the seal around the filler tube and where it meets the filler cap area on the rear 1/4 panel is damaged and allowing it to vent out a bit. when you take you cap off when the tank is nearly empty does it release pressure? if not then it could well be that seal. if it does, then that seal is fine.

as for it being in the exhaust, that would be to do with the tune (even if stock ecu). obviously running rich

Yea wheel arch is near the filler area. Hmm good point, it doesn't vent pressure when I unscrew it. Would replacing the cap cure it? or is the seal part of the filler tube?

Yay

I talked to my tuner today, cars booked in for Major on Saturday to go through all the problems :D

He reckons it's the fuel cap, a common gtr problem, he'll take a look at it anyway.

I can always trust ISMR with my cars.

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
