Hi all, I have a quick question.

Every time I start my engine (93 R33 GTS25T) I get a huge amount of fuel vapor being expelled from the gas tank under the fuel flap, so much and heavy its visible from the top of the wheel arch to the roof line on a still day .

Car is in Queensland so the interior gets very hot in the days.

I have a very bad fuel consumption where a full tank of gas runs out at about 350km. Thats on highway and no hard driving at all....

No boost tap or AM BOV.

I have disconnected the carbon filter in the hope it might have been blocked and pressurizing back in but its still happening.

Cleaned the throttle body and AAC sensor.

Any one have any Ideas on the Fuel venting??

Regards

Have a read of this - clicky

Then check to see whether your fuel filler neck is sealed.

Have you ever noticed fuel down the side of your car after spirited driving with a full tank ?

Do you get the pssshhh sound when you take the cap off ?

Its a pretty common problem that the neck isn't sealed properly

      Wheel Sizes & Offsets For Skylines

      9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.

      Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same.

      I have an elite 2500 running an adapter harness on an rb25de neo r34. I took the butterfly out and removed all that junk. But I also went Plus+t at the same time. The butterfly thing works in reverse to the boost solenoid on the Gtt if that makes sense

      yeh they are 235/45/17 up front and 255/40/17 in the rears. I still didn't get my answer if i can fit a 18x9 up front. I want to get 4 of this and see if they will fit before committing as they didn't see an 18x8 as an option but there is a 18x9.5 also.   Enkei RS05-RR 18x9 35mm ET 5x114.3 75.0 Bore Matte Gunmetal Wheel
