Hi Team..

924S '88 Carbon canister delete.

So, on my 924s, when I take the Vac line off the Fuel Pressure Regulator (FPR) I can smell fuel. There are no drips, leaks when I take off the vac line. I have run the car for a good 15 mins, revved her up, stationary, and still no drips and yet the smell is there. Smoke is normal and not black, though spark plugs are on the dark side but not sooted up. Car feels normal, pulls well and about 25 mpg...though this is normal to me I have never driven another!

I have tested the pressure as per Clarks-garage and all is good.

Is this because of my lack of carbon canister?

Can anyone else confirm if this smell of petrol in the vac line is normal please?

Thanks,

M

Is the FPR diaphragm intact? Suck on it, not looked at 944 prices but a 964 one is nearly £600. I replaced mine a couple of years ago but then spare prices have gone through the roof.

I have sucked on the FPR.....oooo......and have put a hand pump on it and it holds pressure....so does this mean it's good?
Just stumped as to where the fumes are coming from........

There is a hint of petrol fumes in the oil filler.........but...tbh...done very few journeys (10 min max, twice a week) over the last 3 months. Think it may need a proper run to clear out the tubes........M
