Hey guys ive notice a strong fuel smell in my car everytime i hit the throttle? ive did some checks like checking the engine for any smell or leaks but douldnt see any, so i go to look under the car for leaks on exaust etc... still no sign, so checking to see if they are coming from the air vents while window is up still no sign, but once i drive my car with windows down, the strong smell just appears?

any ideas?

cheers

Hows your fuel economy?

I sold my old R33 a while back and it had a similar problem, (could always smell fuel but could never find any leak) the guy who bought it off me said when he got it tuned the oxygen sensor on the exhaust was faulty and it was causing it to run too rich using too much fuel. If you have no fuel leaks and it's not been replaced in the last 40K thenit may pay you to replace it.

Check fuel filler, fuel tank breather lines, etc for perished hoses.

mechanics have tried looking for leaks through the fuel lines etc... but had no clue?

*note* ive got a dump pipe straight of my wastegate welded onto the manifold? could the smell come from the dumpy?

Fuel filler, from what i've read here. A mate of mine had the same thing (very strong smell when cornering) and it ended up being a crack in the rubber surround of the filler... which is added when complianced. (at least on his car it was)

i have the same prob with mine, i noticed a while ago wen i turn the car off i could hear a hissing sound from the fuel cap and the smell seems to be coming from there, going to put a new cap on it now to see if maybe thats the problem, u no, the cap not shutting properly, mite resolve my other acc issues, maybe im losing fuel pressure.just a thot, check it when u turn ur car off, listen to the fuel cap and smell that area.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
